Abstract

PURPOSE:To ensure proper claw engagement with a storage case or the like by fitting a long claw in a carriage travel direction to the tip of a finger laid below a rail and capable of engagement with and disengagement from the storage case or the like via turning motion. CONSTITUTION:When a travel carriage 1 stops at the position of a storage case 21, a lift device 6 is driven and a transfer device 5 is thereby lowered to a level corresponding to the height of the case 21. Then, the motor of the transfer device 5 is driven and a finger 16L turns to the position of a chain line in an arrow direction to keep an approximately level posture. A finger 16R turns as well to the position of the chain line to keep an approximately level posture via interlocked motion with the finger 16L and a rod 20. As a result, the claw 19R of the finger 16R engages with a guide bar 23 at the end of the through-rack 22 of the storage case 21. Then, a conveyor 9 is driven for shifting an article W in a blank arrow direction and the article W is thereby loaded onto the roller 25 of the through-rack 22.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a transfer device that is suspended and supported by a traveling trolley running on rails via a lifting device.

(Prior Art) For example, in a factory assembly line, parts are automatically transported to a predetermined location by a transport device. An example of this conveyance device is shown in FIG. 3, and it is equipped with a traveling trolley 101 that runs on its own along a predetermined route along a mole rail 102. It is supported by hanging.

By the way, the transfer device 105 has a belt conveyor 109, as shown in FIG.
01 (left and right with respect to the running direction), there are fingers 116,
116 is attached so as to be rotatable in the direction of the arrow. Note that each finger 116 has two arms 117, 117.
are connected by rollers IIA and IIS, and a U-shaped claw 119 is fixed to the tip of each arm 117.

In order to transfer the parts W loaded on the transfer device 105 and moved onto the storage case 121 shown in FIG.
It was stopped at position 21, and then the elevator W106
is driven and the parts W are lowered together with the transfer device W105 to the position indicated by the chain line in the figure. Then, the fingers 116, 116, which had been standing vertically, are rotated in the direction of the arrow in FIG.
The 16 claws 119 engage with locking members 123, 123 (only one of which is shown) attached to the end of the storage case 121, thereby preventing the transfer device 105 from swinging.

Then, when the belt conveyor 109 is driven from the above state, the parts W move laterally (in the direction of the arrow in the figure) as shown by the chain line in FIG. It will be transferred.

(Problem to be Solved by the Invention) By the way, in the conventional transfer device 101, each finger 116 is provided with two claws 119° 119 at positions apart from each other. If vibration occurs, only one pawl 119 is attached to the locking member 12.
3, the transfer device 105 could not be reliably assembled into the storage case 121.6 The present invention has been made in view of the above problems, and its purpose is to:
To provide a moving truck transfer device that can be reliably assembled into a storage case or the like when transferring articles.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an article that is suspended and supported by a traveling trolley running on rails via an elevating device, and is carried in a direction perpendicular to the traveling direction of the traveling trolley. In a transfer device that has fingers on the left and right sides of the device that rotate to engage and disengage from article storage cases etc. installed below the rail, the tips of the fingers are provided with the support of a traveling cart. Its feature is that it has long claws in the direction of movement.

(Function) According to the present invention, each finger provided on the left and right sides of the transfer device is attached with a long claw in the traveling direction of the traveling cart, so that when transferring an article, by rotating the finger, the finger can be moved. If any one part of the claw engages with a locking member such as a storage case, the other parts of the claw will sequentially engage with the locking member,
Eventually, all of them will surely engage. As a result, the transfer device can be reliably assembled into the storage case or the like during article transfer, and the transfer can be carried out easily and reliably.

(Example) An example of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a front view of the conveyance device, and FIG. 2 is a side view of the same.
In the figure, l denotes a running trolley, which runs on its own along a mole rail 2 supported on the ceiling of the factory or the like. That is,
The traveling bogie 1 has drive wheels 3 and lower rollers 4.4 shown in FIG.
(only one of which is shown) supports the mole rail 2 so as to sandwich the top and bottom of the mole rail 2, and the drive wheel 3 is rotated by a drive motor (not shown) to run along the mole rail 2 with its own blade.

By the way, the transfer device 5 according to the present invention is suspended and supported at the lower part of the traveling trolley l via a lifting device 5t6. The lifting device 6 has a winding mechanism (not shown) in the housing 7, and a plurality of lifting belts (not shown) are wound or rewound by this winding mechanism.

The transfer device 5 is also attached to the lower end of the lifting belt.

Here, to explain the configuration of the transfer device M5, the transfer device 5
is constructed by incorporating a belt conveyor 9 into a housing 8 forming a rectangular vibrator frame structure.

There are two upper and lower support shafts 10.1 at the front and rear of the housing 8 (front and rear with respect to the traveling direction of the traveling trolley l (horizontal direction in FIG. 2)).
A guide roller 11 is rotatably supported on each support shaft lO.

In the belt conveyor 9, rotary shafts 13, 13 are long in the front-rear direction (left-right direction in FIG. 2) on the left and right sides of the frame 12 (left and right with respect to the traveling direction of the traveling trolley 1 (left and right in FIG. 1)). Two pulleys 14, 14 are connected to each rotating shaft 13, and each rotating shaft 13
．． A flat belt 15, 15 is wound between the opposing pulleys 14 provided on the pulley 13.

Furthermore, fingers 16 are provided at both left and right ends of the frame 12.
L and 16R are rotatably provided. One of the fingers 16R is constructed by connecting arms 17R, 17R which are freely rotatably supported at both ends of the rotating shaft 13 with a roller 18 that is long in the front and back direction. A claw 19R made of an angle member with a long cross-section is installed in a horizontal manner. Note that the other finger 16L is also configured similarly to the finger 16R.

Then,! $1 As shown in the figure, the above finger 16L
and 16R are connected by a rod 20, and an arm 17L of fingers 16L and 16R.

When 17L, 17R, and 17R are all standing vertically as shown by the solid line, one end a of the rod 20 is pivotally attached to the lower left of the rotation axis 13 of the arm 17L.
The other end is pivotally mounted obliquely to the upper left of the rotating shaft 13 of the arm 17R. In this embodiment, frame 1
One finger 16L is rotated by a motor (not shown) built into the finger 2, and the rotation of the finger 16L is transmitted by the rod 20 to the other finger 16R.

By the way, in the transfer device 5, the article W to be conveyed is placed on the belt conveyor 9 as shown in the figure, and when the article W is supported and conveyed by the transfer device 5, the finger 16L and 16R stand vertically as shown by solid lines in the figure to prevent the article W from falling off.

Next, the operation of transferring the article W from the transfer device 5 onto the through rack 22 of the storage case 21 installed on the ground will be described.

When the traveling trolley 1 stops at the position of the storage case 21, the lifting device 6 is driven and the transfer device 5 is lowered to the height of the storage case 21.

Then, a motor (not shown) built into the frame 12 of the transfer device 5 is driven, and one finger 16L is moved to the first position.
Either the finger 16L is rotated so as to be substantially horizontal in the direction of the arrow in the figure to the chain line position, or the rotation of the finger 16L is transmitted to the other finger 16R via the rod 20, so that the finger 16R is also The finger 16R is rotated until it is approximately horizontal to the position shown by the chain line in FIG.
It engages with a guide bar 23 that is long supported in the front-rear direction (perpendicular to the plane of the paper in FIG. 1) at the end of the through rack 22.

At this time, since the claw 19R is single and long in the length direction of the guide bar 23, if any one of the claws 19R partially engages with the guide bar 23, the other claws 19R The parts also engage with the guide bar 23 one after another, and eventually all of them engage with the guide bar 23 reliably. As a result.

Transfer equipment! 15 is reliably assembled to the through rack 22.

If the belt conveyor 9 is driven from the above state and the article W placed thereon is transferred in the lateral direction (in the direction of the arrow in FIG. 1), the article W is moved to the guide 24 supported by the housing 8. 24, and is transferred onto the rollers 25 of the through rack 22 via the lot 18 of the finger 16R. At this time, since the transfer device 5 is reliably assembled to the through rack 22 as described above, the article W can be transferred onto the through rack 22 easily and reliably.

(Effects of the Invention) As is clear from the above description, according to the present invention, articles are suspended and supported by a traveling trolley running on rails via an elevating device, and are carried in a direction perpendicular to the traveling direction of the traveling trolley. In a transfer device that has fingers on the left and right sides of the device that rotate to engage and disengage from article storage cases etc. installed below the rail, the tips of the fingers are provided with the support of a traveling cart. Since long claws are attached in the direction of travel, if one part of the claw engages with a locking member such as a storage case by rotating the finger when transferring an item, other parts of the claw will also engage in sequence. By engaging with the stop member, the transfer device can be reliably assembled into a storage case or the like during article transfer, and the article can be transferred easily and reliably.
