Description

Description: TECHNICAL FIELD The present invention relates to a horizontal / vertical transfer device using an endless chain, and particularly, when an object to be transferred is placed on a pallet table, the interval between the pallet tables is small. This eliminates the inconvenience of the transferred object dropping from the pallet table, and returns to the normal interval when moving from the horizontal transfer line to the vertical transfer line to prevent the pallet tables from colliding.
The present invention relates to a vertical transport conveyor device.

[Conventional technology]

A plurality of pallet tables are rotatably arranged side by side at predetermined intervals on a roller link plate of an endless chain, and the objects to be transferred are successively placed on the pallet tables and transferred in the horizontal and vertical directions. A horizontal / vertical conveyor device of this kind is known.

According to this apparatus, if the interval between the pallet stands is set too large, the transferred object falls from between the pallet stands at the mounting position, so that the interval between the pallet stands must be reduced as much as possible. However, there is no problem if the conveyor device is composed only of the horizontal transfer line. There is a problem that the transferred objects fall from the pallet table due to impact when the clubs collide with each other. In addition, there is a problem that the pallet tables collide with each other when shifting to the vertical transfer line, thereby shortening the life of the pallet tables and the entire conveyor device. In order to solve the above problems, for example,
There are those disclosed in JP-A-51-11399 and those disclosed in JP-A-61-12505. However, the former requires a special chain due to its configuration,
It is not possible to easily create a place where pallet stands approach each other only in an arbitrary small area, and it is not easy to change the position. In the latter case, although a special chain is not required, the bucket moves up and down during the horizontal transfer and becomes unstable during the horizontal transfer because the chain has a zigzag shape at the horizontal transfer position.

[Problems to be solved by the present invention]

As described above, the conventional conveyor has various problems, and therefore, according to the present invention,
Horizontal / vertical transport that can effectively prevent the transferred object from falling when it is placed or taken out, and can easily create or change the horizontal transfer line where the transferred object is placed or taken out. It is an object to provide a conveyor device.

[Means for solving the problem]

The present invention relates to a horizontal / vertical transport chain conveyor device in which a pallet table moves on a horizontal transfer line and a vertical transfer line. When the chain is engaged, the chain conveyor passes below the horizontal transfer line. In the horizontal transfer line, the pallet table is moved on the horizontal guide rail by rollers provided on the pallet table and provided on the chain side. The crank plate and the crank plate provided on the roller side are rotatably mounted.

[Action]

 The present invention has the following operation.

Since the chain conveyor passes below the horizontal transfer line due to the engagement of the chain and the sprocket, the pallet tables located in front of and behind the sprocket approach each other, but the pallet table is moved horizontally through the crank plate. Since it moves on the rail, it does not move up and down during horizontal movement. That is, in the horizontal transfer line in this conveyor device, the pallet table moves horizontally without moving up and down. Then, when shifting to the vertical transfer line, a predetermined interval is maintained between adjacent pallet stands, so that the front end of the succeeding pallet stand does not contact the rear end of the preceding pallet stand.

Further, by simply providing a sprocket on the chain portion in the horizontal transfer line, a place where the pallet stands approach each other can be easily formed or changed at an arbitrary place.

〔Example〕

Hereinafter, a specific configuration of the apparatus of the present invention will be described in detail based on the illustrated embodiment.

FIG. 1 is a schematic side view showing an example of the apparatus of the present invention. In FIG. 1, reference numeral 1 shows an endless chain conveyor having a horizontal transfer line H and a vertical transfer line V. 2 is a plurality of pallet tables attached to the chain conveyor 1 at predetermined intervals,
3 is a driving sprocket for the chain conveyor 1, 4 is a driving device for the sprocket 3, 5 is a chain conveyor 1
Auxiliary sprockets 6 arranged in the vicinity of the corners indicate guide rails for holding the upper surface of the pallet table 2 in a horizontal state when the pallet table 2 passes the vertical transfer line V. Is placed on the pallet table 2 at the position shown in FIG. 1A at an appropriate position on the horizontal transfer line H, and the vertical transfer line V or another horizontal transfer line H
And is conveyed to the target position.

As described above, when the objects to be transferred are continuously placed on the pallet table 2, if the objects to be transferred are relatively small, the interval between the pallet tables 2 at the mounting position is too large. In such a case, there is a problem that the transferred object falls from a gap between the rear end of the preceding pallet table 2 and the front end of the subsequent pallet table 2. On the other hand, when the pallet tables 2 are attached to the chain conveyor 1 with a reduced interval between them to eliminate this problem, the pallet tables 2 collide when the pallet tables 2 move from the horizontal transfer line H to the vertical transfer line V. Problems arise.

According to the present invention, when the object to be transferred is placed on the pallet table 2 on the horizontal transfer line H, the interval between the pallet tables 2 becomes narrower and the vertical transfer line V This is to provide a chain conveyor device in which an interval such that the pallet tables 2 do not come into contact with each other at the time of shifting is provided. Based on FIG. 2 which is an enlarged side view of a portion indicated by A in FIG. The details of the device will be described.

In FIG. 2, reference numeral 7 denotes a sprocket arranged on the horizontal transfer line H so as to mesh with the upper surface side of the chain roller. When the chain roller meshes with the sprocket 7, the chain conveyor 1 moves the horizontal transfer line H downward. It is designed to bypass. Note that the detour distance can be changed by adjusting the height of the support shaft of the sprocket 7 or changing the size of the sprocket 7. If a pair of auxiliary rollers 8, 8 for supporting the chain conveyor 1 is provided below the sprocket 7, the stability is improved. The upper part of the horizontal transfer line H on which the sprocket 7 is provided is set as a position where the object to be transferred is placed on the pallet table 2. When the sprocket 7 meshes with the upper surface of the chain roller, the chain conveyor 1 becomes horizontal. Since it passes below the transfer line H, the interval S between the pallet tables 2 connected to the roller link plate 9 at predetermined intervals becomes small,
It is possible to solve the problem that the transferred object falls downward.

On the other hand, since the chain conveyor 1 having passed through the sprocket 7 returns to the normal horizontal transfer line H, the interval between the pallet tables 2 is maintained as originally set. It is possible to prevent two friends from colliding with each other.

FIG. 3 is a detailed perspective view of the periphery of the pallet table. In FIG.
Is a rotating shaft supported by the pillow block 10, 12 is a roller provided at the tip of the rotating shaft 11, and 13 is a pallet table 2.
Auxiliary rollers provided on the other side of the lower surface, 14 is a guide rail disposed on the horizontal transfer line H, 15 is a chain conveyor receiver, 16 is a chain roller, and 17 is fixed to the roller link plate 9 so as to form a right angle. Attachment,
Reference numeral 18 denotes a guide pin fixed to the attachment 17, and the guide pin 18 and the rotating shaft 11
Are rotatably connected via a.

Therefore, the upper surface of the pallet table 2 is
In addition, the horizontal state can always be maintained during the movement of the vertical transfer line V.

That is, while moving along the horizontal transfer line H, the guide rail 14
The roller 12 and the auxiliary roller 13 are supported thereon, the crank plate 19 is bent at a right angle, and the pallet table 2 is maintained in a horizontal state. The auxiliary roller 13 is guided by the guide rail 6, the crank plate 19 becomes horizontal, and the pallet table 2 maintains a horizontal state.

Although the above embodiments have been described in relation to the placement position of the object to be transferred, the sprocket 7 for detouring the chain conveyor 1 downward is also provided at the position shown in FIG. Needless to say, it is possible to prevent the transferred object from dropping when the transferred object on the table 2 is taken out.

〔The invention's effect〕

In the conveyor device according to the present invention, when the horizontal transfer line is set to the loading position or unloading position of the object to be transferred, the interval between the pallet stands is narrow only at the position, and the pallet stands are moved horizontally without any vertical movement. Therefore, it is possible to effectively prevent the transferred object from falling when being placed or taken out. In addition, the horizontal transfer line can easily create or change the placement position or take-out position of the transferred object.
