(b) A means of lifting an object on a moving transport block using a lifting device such as a vacuum suction device, moving it above the container, and lowering it into the container.

(b) One side of the conveying block is rotatably attached to the conveyor, and the other side of the conveying block is guided by a guide rail arranged parallel to the conveyor to maintain the posture of the conveying block and keep it at a predetermined location. A method of tilting the conveying block by gravity while guiding it by a guide rail, and causing an object placed on the conveying block to fall into a container by gravity (see Japanese Utility Model Publication No. 37742/1983).

(c) A conveyance block having a plurality of rollers rotatably supported is provided on the conveyor, an object is placed on the plurality of rollers, and the conveyance block is moved;
At a predetermined location, each roller is rotated by moving while contacting a plate fixed below, and the rotation causes the object to move in the direction of movement at a speed twice the speed of the movement. (Utility Application No. 47-72647 [Utility Model Application No. 49-31088])
reference).

[Problems to be Solved by the Invention] Among the above-mentioned conventional techniques, the one (a) has a problem in that a lifting device such as a vacuum suction device is required.

The method (b) has the problem that it is difficult to place the object in a predetermined location on the container because the object falls from the transport block into the container due to gravity.

In the case of (c), the object is sent from the transport block to the container etc. at twice the speed of the movement of the transport block in the direction of movement of the transport block, so the object is sent out forcefully to the fixed container. There is a problem that it gets lost.

The present invention has been made in view of the above-mentioned problems of the conventional technology, and it is possible to reliably place an object placed on a transport block in a predetermined location such as a container without using a lifting device. The object is to provide an object transfer device.

[Means for Solving the Problems] To achieve the above object, an object transfer device of the present invention rotatably supports a rotating body for placing an object between two opposing side plates, and each of the side plates A conveyor block is provided with a protrusion protruding outwardly at one end thereof, and a guide roller protruding outwardly at the other end of each of the side plates, and each protrusion of the conveyor block is provided with a guide roller protruding outwardly. A pair of endless band-like members that support and move the transport block from the guide roller toward the protrusion are disposed parallel to each other, and a pair of guide rails that respectively guide each guide roller of the transport block are arranged in parallel with each other. are arranged in parallel with the belt-shaped members, respectively, and each of the pair of guide rails is provided with a separated portion in a portion of the pair of guide rails, where the pair of guide rails moves away from the pair of belt-shaped members, then approaches the pair of belt-shaped members, and returns to the original distance; A presser plate for rotating the rotating body of the block is placed in a position where it comes into contact with the rotating body of the conveying block from the side on which the object is placed when each guide roller of the conveying block is guided to each of the separated portions. It is characterized by being fixed.

In addition, some devices are equipped with a plurality of transport blocks.

Furthermore, the rotating body on which the object is placed is a plurality of rollers arranged parallel to each other, and belts are wrapped around adjacent rollers to rotate in conjunction with each other. There are two rotatable bodies arranged parallel to each other at both ends of each side plate.
Some are wide belts wrapped around individual rollers.

[Operation] In the object transfer device of the present invention configured as described above, the object is placed on the rotating body of the transport block, and the transport block is supported by a pair of belt-shaped members each of which has a non-striped protrusion. direction of the protrusion from the guide roller (hereinafter referred to as the "movement direction")
will be moved to The attitude of the conveyance block during movement is kept constant because each guide roller of the conveyance block is guided by a pair of guide rails each disposed parallel to a pair of band-like members.

[Example] An embodiment of the present invention will be described based on the drawings.

FIG. 1 is a schematic sectional view of this embodiment, and FIG. 2 is a perspective view of the conveyance block of this embodiment.

First, the transport block 3 shown in FIG. 2 will be explained. A plurality of rollers 6 (seven in the figure) arranged parallel to each other are rotating bodies on which objects are placed.
is rotatably supported between two opposing side plates 3a and 3b. A belt 9 is wrapped around adjacent rollers 6 to rotate in conjunction with each other, so that the rotation of the roller 6 at one end is transmitted to the roller 6 at the other end. It's summery.

A protrusion 6a is provided at one end of each side plate 3a, 3b.
(others not shown) are respectively provided to protrude toward the outside, and guide rollers 7 (others not shown) that protrude outward are provided at the lower part of the other end.

In FIG. 1, a pair of endless strip members 1 (others not shown), generally made of chains, are arranged parallel to each other, and the running path on the upper side of the figure is a frame 8 (not shown in FIG. 1). (see Figure 3), each is held horizontally. Further, the pair of band-like members 1 are moved by the arrow A by driving a motor or the like (not shown).
It is configured to be moved in the direction.

A pair of guide rails 2 with a U-shaped cross section
(others not shown) are arranged in parallel with the pair of band-like members 1, respectively, and a pair of guide rails 2 extend from the pair of band-like members 1 at the upper horizontal part of the pair of guide rails 2 in the figure. Separated portions 2a (the others are not shown) are each formed in a shape that descends and moves away, moves horizontally for a while, then approaches and returns to the original distance.

The transport block 3, as shown in FIG.
Each protrusion 6a is supported by a pair of band-shaped members 1, and each guide roller 7 is fitted into and supported by a pair of guide rails 2, respectively. In the transport block 3, each protrusion 6a is engaged with a pair of protrusions 1a (others not shown) provided on the pair of band-like members 1, so that the pair of band-like members 1 move in the direction of arrow A. Accordingly, the transport block 3 is moved in the direction of arrow A, and each guide roller 7 is guided by the pair of guide rails 2, so that the posture of the transport block 3 during movement is maintained.

A presser plate 5 (see FIG. 1 or 4) for rotating each roller 6 of the conveyance block 3 is fixed above each separated portion 2a of the pair of guide rails 2. When each guide roller 7 of the transport block 3 is guided to each separated portion 2a, the position is from the circumferential surface of the roller 6 on the protrusion 6a side of the transport block 3 and the side on which the object 11 is placed. This is the position of contact.

At the bottom of the horizontal portion of each separated portion 2a (see FIG. 1) on the right side in the figure, there is a container 4 such as a pallet.
In addition, a delivery conveyor 10 for delivering a flat object 11 to a conveyance block 3 is provided at a portion where a pair of belt-like members 1 rise from below and become horizontal, as shown at the right end of the figure. ing.

Next, the operation of this embodiment will be explained. As shown in FIG. 1, when a flat object 11 is sent by the delivery conveyor 10,
receives this object 11 at the right end position in the figure and conveys it in the direction of arrow A. At first, the pair of belt-like members 1 and the pair of guide rails 2 are both horizontal, so the conveyance block 3 moves while maintaining a horizontal posture.
When reaching point a, each guide roller 7 of the transport block 3
are guided to the respective separated portions 2a, and the rear portion of the transport block 3 on the guide roller 7 side descends (see FIGS. 1 and 4). Even in this state,
Since each protrusion 6a of the transport block 3 is moved horizontally by the pair of belt-like members 1, the transport block 3 is moved obliquely as shown in the figure.

Further, since the rollers 6 on the protruding portion 6a side of the transport block 3 move while contacting the presser plate 5, the friction force causes them to rotate in the opposite direction to the moving direction of the transport block 3, and as a result, all the rollers 6 are rotated in each direction. Rotating in conjunction via the belt 9, the object 11 is forced into the container 4 in a direction opposite to the direction of movement of the transport block 3 at the same speed as its movement relative to the transport block 3.

When the inclined transport block 3 is further moved in the direction of arrow A, each guide roller 7 is guided by the pair of guide rails 2 and returns to a horizontal position, which is the receiving position for the object 11 described above. Return to the right end of Figure 1.

The conveyor block 3 transports the object 11 onto the delivery conveyor 1.
0, the object 11 is stopped at the receiving position at the right end in FIG. and begin to move while receiving the object 11.

The transport block 3 that has received the object 11 performs the above-described transfer operation to send the object 11 to the container 4, and then returns to the receiving position and stops.
Wait for the next object 11 to be sent out.

If it is not possible for the transport blocks 3 to return to the receiving position in time before the delivery conveyor 10 sends out the next object 11, two or more transport blocks 3 are attached to the pair of belt-like members 1 in the required number.

In this way, the transfer operation can be performed at the same time interval as when the object 11 is sent out.

FIG. 5 shows another embodiment of the conveying block of the present invention. Between the two opposing side plates 13a and 13b of the conveyance block 13, each side plate 1
Two rollers 16, 16 are installed at both ends of 3a, 13b.
are rotatably arranged parallel to each other, and a wide belt 20 serving as a rotating body for placing an object is wrapped around the two rollers 16, 16. In this case, the object 11 is the wide belt 2
0 and processed.

[Effects of the Invention] Since the present invention is configured as described above, it produces the effects described below.

When each guide roller of the transport block is guided to each separated part of the pair of guide rails,
The conveyance block is tilted from a fixed posture, and the object placed on the rotating body of the conveyance block is
It is forced out of the transport block in the opposite direction to the direction of movement of the transport block at the same speed as the speed of its movement.

As a result, the object placed on the transport block
It is possible to reliably send out the product from the transport block without using a lifting device such as a vacuum suction device, and without particularly requiring gravity. Furthermore, if a container or the like is properly fixed at a location where each guide roller of the transport block is guided to each of the separate parts, the object is transported so that it is left quietly with almost no relative speed to the container or the like. Since the block is delivered to a container or the like, the object can be reliably placed in a predetermined case such as a container.
