Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transport redirection device.

In a conventional transfer direction changing device, one end of a vertically movable frame is rotatably attached to a fixed support, and a cam for vertically moving the vertically movable frame is attached to the fixed support, and this cam is driven. The motor and the motor that drives the transfer mechanism provided on the vertically moving frame are respectively fixed, and the transfer mechanism of the vertically moving frame is arranged to intersect with other transfer mechanisms and move up and down, thereby forcibly moving the transferred object. Although the conveyance direction is changed, if the fixed support is provided with a cam, a motor, etc., as in this conventional device, the fixed support becomes large and difficult to transport and assemble.

The present invention was made in view of these points,
By providing the vertical movement mechanism of the vertically movable frame body on the vertically movable frame body itself, the conventional large fixed support body is made unnecessary.

Next, one embodiment of the present invention will be described based on FIGS. 1 to 3.

A pair of bearings 2 is provided at the upper end of one of the fixed supports 1, and one part of a vertically movable frame 4 is rotatably mounted via a shaft 3 rotatably supported by the bearings 2. This vertically movable frame 4 is made by integrating a pair of side plates 5 in the shape of an inverted isosceles triangle by connecting plates 6, 7, etc., and a recess 8 is cut into the center of the side plates 5 from above. .

Further, one transfer mechanism 11 is provided on the vertically movable frame 4. One of the transfer mechanisms 11 includes a shaft 12 supported between the side plates 5 on both sides by bearings, respectively.
13, 14, 15, 16 are rotatably installed, and sprocket wheels 17, 18, 1 are installed on both sides of the shafts 12, 13, 14, 15, 16 and the shaft 3.
9, 20, 21, 22 are fixed, and the sprocket wheels 17, 18, 19, 20, 21,
An endless chain 23 for transfer is wound around each of the connecting plates 22 along the outer shape of the side plate 5, and the connecting plate 6
A sprocket wheel 2 is installed between the output shaft 25 of the motor 24 and the shaft 3.
6, 27 and an endless chain 28, and the upper rotating part of the endless chain 23 for transfer is made to protrude upwardly from the side plate 5 and along the side plate 5 across the recessed part 8. The upper surface of the endless chain 23 forms a transfer surface. A pair of bearings 31 are fixed to the lower surface of the connecting plate 7 installed on the other side of the vertically movable frame 4, and the rotating shaft 32 is connected via the bearings 31. A supporting portion 33 is integrally provided downwardly from the connecting plate 7, and the rotating shaft 32 is supported rotatably on the supporting portion 33.
fixing the motor 34 as a drive source for driving the
A power transmission section consisting of sprocket wheels 36, 37 and an endless chain 38 is provided between the output shaft 35 of the motor 34 and the rotating shaft 32.

Further, disk-shaped rotating bodies 41 are fixed to both sides of the rotating shaft 32, and the upper part of the rocking body 42 is rotatably attached to eccentric positions of the rotating bodies 41 on both sides via pin shafts 43, The lower part of this rocking body 42 is rotatably attached to the other fixed support body 44 via a pin shaft 45.

The other fixed support 44 is a horizontal frame installed between support frames 47 on both sides of the other transfer mechanism 46, and the other transfer mechanism 46 is connected to the rising level of the transfer surface of the one transfer mechanism 11. A transfer chain 48 is provided along the support frame 47 that intersects with one of the transfer machines 11 at right angles at a certain height level between the descending level and the chain 48.
is driven by a motor (not shown). Note that one support frame 47 of the other transfer mechanism 46 is fitted into the recess 8 of the vertically movable frame 4 so as not to prevent the vertically movable frame 4 from vertically moving.

Then, for example, an object 52 such as a pallet is transferred from the general entry section 51 connected to the left end of the vertically movable frame 4 onto one of the transfer mechanisms 11, and the endless chain 23 of this transfer mechanism 11 is moved. The transfer mechanism 46 is driven to position the object 52 thereon above the other transfer mechanism 46 .

At this time, the rotating shaft 32 is rotationally driven by the motor 34 and is located further above the pin shaft 43 which swings at a substantially constant level around the pin shaft 45 in a fixed position. Since the transfer surface of one transfer mechanism 11 supported by the shaft 3 is rotated above the transfer surface of the other transfer mechanism 46, the transfer surface of one transfer mechanism 11 supported by An object 52 to be transferred can be transported above the transfer mechanism 46 of the transfer mechanism 46 .

Subsequently, the rotating shaft 32 is located below the pin shaft 43, which is rotated by the motor 34 and swings at a substantially constant level around the pin shaft 45 in a fixed position, and as a result, this rotation Axis 3
Since the transfer surface of one transfer mechanism 11 supported by the transfer mechanism 2 is rotated at a position lower than the transfer surface of the other transfer mechanism 46 about the shaft 3, the transferred object 52 is transferred from one transfer mechanism 11 to the other. The other transfer mechanism 16 forces the other transfer mechanism 16 to carry out the transfer in a different transfer direction.

Next, in the above embodiment, one part of the vertically movable frame 4 was rotatably attached to one of the fixed supports 1, but instead of this structure, both parts of the vertically movable frame 4 were attached to the fixed support 1. The vertically movable frame 4 may be similarly supported via a rotary body 41 or the like to horizontally move vertically.

That is, as shown in FIG. 4, the rotating shafts 32, 32a are connected to each other through the connecting plates 7, _7a and bearings (not shown) in both parts of the vertically movable frame 4 provided with one of the transfer mechanisms 11 _. In addition to rotatably supporting the

The upper part of _a is rotatably attached to pin shafts 43, _43a , and the lower part of both rocking bodies 42, _42a is connected to the fixed support 44 of the other transfer mechanism 46 for carrying out and the carrying-in conveyor 61, respectively.

The one in Figure 4 is an endless chain 38,3
Although both rotating shafts 32, _32a are synchronously driven by _8a , a link or the like may be used as the synchronization mechanism.

Furthermore, the motor 34 as a driving source may be replaced by an air cylinder actuator or the like.

As described above, according to the present invention, the drive unit such as the motor, rotating shaft, rotating body, and rocking body, which were provided in the conventional fixed support body, is integrated into the vertically movable frame body, and the vertically movable frame body Since there is no need to provide a drive unit such as the motor or rotating body on the fixed support that supports the Since the frame bodies of the carry-in conveyor and the carry-out conveyor can be used as the body, the conventional fixed support can be completely unnecessary, and there are also advantages that cost reduction is possible and wiring is easy.

Further, the rotating shaft is rotatably supported by the vertically moving frame, and a drive source for driving this rotating shaft is integrally provided in the vertically moving frame, the rotating body is fixed to the rotating shaft, and the eccentricity of this rotating body is Since one part of the oscillator is rotatably attached to a fixed support, and the other part of the oscillator is rotatably attached to a fixed support, it is possible to change the axially attached position of the oscillator relative to the rotating body. Therefore, the vertical movement stroke of the vertical movement frame can be easily changed, and a large vertical movement stroke can be easily obtained. Furthermore, because of the swinging body, the vertically movable frame can be moved up and down almost vertically.

In addition, if both parts of the vertically movable frame are driven synchronously by a rotating shaft, a rotating body, a rocking body, etc., the vertically movable frame can be horizontally moved up and down.
The direction of the transferred object can be reliably changed with a slight vertical stroke.
