Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load holding device for a balancer device, which has a function of supporting a heavy object at an arbitrary working position in an equilibrium state, and more particularly to a suction type holding device capable of changing a holding angle. Regarding

[0002]

2. Description of the Related Art Conventionally, various balancer devices (also referred to as balanced cargo handling devices, etc .; hereinafter simply referred to as balancers).
Is provided and is used as an auxiliary device in assembling heavy objects such as various assembly lines. FIG. 4 shows an example of a conventional balancer. To explain this, a fixed or movable base 100 is provided with a power unit 101 and a control unit 102, and controls an arm 104 having a joint 103. ing. A horizontal support base 105 is provided at the tip of the arm 104, and the operation switch 106
By operating the etc., it is possible to perform movements such as ascending, descending, turning and the like.

Therefore, by providing the load holding device 107 on the horizontal support base 105, the load 110 held thereby can be moved. Further, by setting the operation switch 106 and the like to the neutral position, the load 110 can be placed in an equilibrium state, that is, in a weightless state (load amount Wo = lifting force Fo by the arm). By pushing, it can be moved to any position.

The load 110 is held by suction of the adsorbent 108 installed in the load holding device 107. The adsorbent 108 is a suction cup-shaped pad, and can hold a load by performing suction, and can release the load by stopping suction.

With such a construction, if the load has a flat plate-like portion which can be sucked, the load can be held very easily by adsorbing the load near the center of gravity regardless of the shape. For this reason, there are advantages such as not requiring a connecting operation with a string, a hook, etc. and not damaging a load,
Therefore, it is effective when it is desired to move a load to a desired position in a short time such as on a production line.

[0006]

By the way, in the conventional load holding device, when the monitor television unit 112 is held and moved as shown in FIG. 5A, the CRT surface 113 is always in the horizontal direction. Is maintained. Therefore, as an example, although it is suitable when the monitor television 112 is incorporated in the horizontal plane display type video game machine 115 shown in FIG. 5B, the slope display type video game machine 117 as shown in FIG. 5C or , Fig. 5
It is extremely difficult to incorporate the monitor television 112 into the vertical plane display type video game machine 118 as shown in FIG.

That is, at this time, the slope display type video game machine 117 or the vertical display type video game machine 1 is used.
On the verge of incorporating the monitor television 112 into 18,
It is necessary to stop the adsorption to the monitor television 112 by the adsorption holding device 109 and release the holding. As a result, it is necessary to re-hold the monitor TV 112 by the hand of the operator and perform the mounting / inserting operation.

The monitor television 112 is usually a 26-inch C or the like.
Since it is a heavy object equipped with an RT (Cathode Ray Tube), it is necessary to secure multiple workers, which not only impairs the rationalization of production, but also imposes an unreasonable posture, which causes work such as backache and fall. This causes safety problems and also quality problems such as product damage. To solve this problem, it is desired that the holding angle of the suction holding device 109 can be changed to a desired angle. However, there is no adsorption-holding balancer capable of changing the holding angle from horizontal to vertical.

Further, according to the suction holding device, although it is possible to hold the suction portion even if there is some deviation, the holding is easy, but it is difficult to accurately hold the position of the load. Means that it becomes difficult to accurately mount the device.

In view of the above problems, the present invention makes it possible to move the object to be supported from the horizontal direction to the vertical direction by changing the attachment angle of the suction type holding device, and attach the heavy object to the equipment. A first object is to obtain a balancer with a suction holding device capable of expanding a possible range, and a second object is to obtain a variable angle angle holding device for a balancer, which can hold a holding position of a supported object constant. I am trying.

[0011]

In order to achieve the above object, in a variable angle angle holding device for a balancer according to the present invention, a load supporting portion provided at a tip end portion of a movable arm, In a balancer support part having a holding means for holding an object to be supported by a suction mechanism and having a mechanism capable of maintaining an equilibrium state with a load held by the holding means, the support part is provided with the holding means. A means is provided which is provided with an angle adjusting mechanism capable of changing the load holding angle by 90 degrees or more.

According to a second aspect of the present invention, the load support section includes a horizontal support base, an adsorbent base section rotatably mounted at an angle of 90 degrees or more with respect to a vertical direction of the horizontal support base, a cylinder base and A cylinder rod end portion is provided between the adsorbent base portion and the horizontal support base, and the adsorbent base portion is movably installed between a horizontal position and a vertical position by expansion and contraction of the cylinder rod. A cylinder is provided, and in the claim 3, the adsorbent base is provided with a bracket that can bear the weight of the load held by the adsorbent.

[0013] In other words, it has a holding portion by an adsorbent, which is rotatably held by a supporting portion capable of maintaining an equilibrium state, and a cylinder capable of changing the supporting portion and the holding portion by 90 degrees or more. A bracket that can bear the weight of the supported object in the vertical position may be provided.

The angle adjusting mechanism is a mechanism capable of adjusting the angle of the holding means by 90 degrees or more, and includes any actuator such as a fluid cylinder or a screw jack.
Due to the nature of the balancer, the horizontal support base is a load support part that maintains a constant posture even when the position of the arm (Arm) changes, while maintaining a horizontal plane with respect to the balancer installation surface. An adsorbent, which includes a movable support part and includes a case where the adsorbent is not horizontal, is a suction cup-shaped object or the like and has a function of adsorbing to an object by sucking the inside and applying a negative pressure. Means a plate shape or a circular shape. The adsorbent base is a trapezoidal portion in which a plurality of adsorbents are provided, and the arrangement of the adsorbents, the flat shape of the trapezoidal portion, the curved shape, or the like does not matter.
Brackets are overhanging plates, receivers, etc. that, in the case of a plate-shaped load, protrude above the adsorption surface of the adsorbent and do not protrude depending on the shape of the load. A part or part that can be supported.

[0015]

With the above construction, the load held by the suction mechanism of the support portion can be changed in its holding angle by 90 degrees or more by the angle adjusting mechanism. In claim 2, the load held by the adsorbent on the adsorbent base is against the horizontal support base by the cylinder,
It can be changed from the horizontal position to the vertical position or more together with the adsorbent base. In the third aspect, the weight of the load held by the adsorbent is carried by the bracket at the vertical position of the adsorbent base, and the adsorption force required for holding by the adsorbent is reduced. Moreover, since the bracket position is a fixed position of the load, the position of the load can be grasped.
