Abstract

PURPOSE:To secure such a conveyor that is usable through pushing operation by constituting it with a chain fitted with a horizontal roller and a vertical roller, a chain guide with a contact surface contacting with both these rollers respectively, and a device attaching a conveying material to a chain tip. CONSTITUTION:When a sprocket is driven and a conveyor is used by pulling it, a horizontal roller 13 comes into contact with a horizontal roller contact surface 22 of a chain guide 21, and a vertical roller 15 also comes into contact with a contact surface 23 of the chain guide 21 and is drawn in the sprocket direction as being corrected of its forward direction, thereby pulling nearer a conveyed material 32 attached to a hook 59. When pushing the conveyor contrariwise, it is pushed in direction of separating from the sprocket so that the horizontal roller 13 and the vertical roller 15 come into contact with these contact surfaces 22, 23 of the chain guide 21 respectively, and they are pushed to the opposite direction to the sprocket as being corrected of their directions. With this constitution, the conveyor is usable by pushing together with pulling the other way.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a conveyor, specifically a conveyor that can be used with one end in a free state and pushed out from the other end, and a conveyor equipped with the conveyor.

(Prior Art) Conventionally, conveyors have generally been constructed in an endless manner, and have been used by applying driving force through sprockets and driving the conveyor while being pulled by the sprockets. and,
When objects to be transported are moved back and forth in both directions, the endless conveyor is rotated in forward and reverse directions repeatedly.

(Problem to be solved by the invention) If an object is to be transported between positions where the positional relationship does not always change, it is sufficient to install one conveyor between both positions and move the object back and forth. .

However, if a conventional endless conveyor is used, if the object is to be conveyed when the object moves and changes its position and reaches a specific position, it is necessary to install two or more conveyors.

For example, a mold is taken out from a mold storage area (1ot) where a plurality of molds are installed, as shown in the plan view in FIG.
2) In providing a mold suitable for each work such as C,
Mold storage area (101,) and processing machine (102) a
, (102) b, and (102) c.
This is the case of transportation in step 4). In this case, if a conventional endless conveyor is used, the conveyor (104) and
Processing machine (102) a, (102) b, (10
2) Fixed trolley (105) fixed in front of c,
Endless conveyors (106) a and (106) b are attached to (105) b and (105) c, respectively.
.

It was necessary to install (106)cl(106)d.

In the first place, if the mold is moved without a conveyor, the burden on the worker will be heavy if the mold is heavy.

Therefore, the fixed trolley (105) a, (+05) b
, (105) In C, only a chain guide for conveying the chain is installed, the chain and the sprocket for conveying the chain are installed on the conveyance trolley (104), and the chain is made cantilevered and the chain is fixed on the trolley (105). a, (
105) b, (105) c, processing machine (102)
It is also possible to use it by expanding and contracting it in the direction. That is, the molds are processed by machines (102) a, (102) b, (1
02) When moving in the c direction, the chain is pushed by a sprocket, and when moving the mold toward the carrier (104), it is pulled by a sprocket.

However, conventional conveyors are generally designed to be pulled by sprockets. When it is pulled and used, tension is applied and the direction of movement becomes a driving means, and the direction of movement remains constant. However, when using a conventional conveyor by pushing it, the direction of movement of the conveyor cannot be determined just by pushing it with the drive means.
The problem was that the direction of movement of the chain tip was not determined.

(Means for Solving the Problems) The present invention provides a chain to which a horizontal roller is installed so that the axis of rotation is horizontal, and a vertical roller is installed so that the axis of rotation is vertical, and a horizontal roller. A conveyor comprising: a chain guide provided with a horizontal roller contact surface that contacts the vertical roller; and a vertical roller contact surface that contacts or is provided close to the vertical roller; and an attachment means that is attached to the tip of the chain. and a storage area for objects to be transported, and a plurality of processing machines installed opposite to the storage area for objects to be transported and having intermediate carts in front of the processing machines; 1. It consists of a transport vehicle that can move between the storage area for the transported object and the processing machine, and the transport vehicle has a horizontal roller installed so that the axis of rotation is horizontal, and a vertical roller installed so that the axis of rotation is vertical. A chain that can be attached to a roller,
Installing a conveyor consisting of a chain guide provided with a horizontal roller contact surface that contacts a horizontal roller and a vertical roller contact surface that is provided in contact with or close to a vertical roller, and an attachment means that is attached to the tip of the chain,
The intermediate truck is provided with a conveyor characterized in that a chain guide is provided with a horizontal roller contact surface that contacts the horizontal roller and a vertical roller contact surface that is provided in contact with or near the vertical roller. We solve traditional problems by providing transportation equipment.

(Function) When the conveyor is pulled, the conveyor is pulled in the direction of the driving means, so the horizontal rollers are in contact with the horizontal roller contact surface of the chain guide, and the vertical rollers are also in contact with the vertical roller contact surface of the chain guide. While adjusting the direction of travel while making contact with the
When the object to be transported is attached to the attachment means, the object to be transported is drawn toward the driving means.

When the conveyor is pushed, the conveyor is pushed away from the drive means, so the horizontal rollers are in contact with the horizontal roller contact surface of the chain guide, and the vertical rollers are also in contact with the vertical roller contact surface of the chain guide. When the object is pushed in the opposite direction to the driving means while the direction is being corrected, and the object to be transported is attached to the attachment means, the object is transported in the opposite direction to the driving means.

In the invention as set forth in claim 2, the conveyance vehicle is moved to the conveyed object storage position, and the conveyed object is locked by directing the tip of the attachment means toward the conveyed object. Then, the driving means is driven in a direction to push out the chain. Then, the conveyor is pushed in the direction away from the drive means, so the horizontal roller is in contact with the horizontal roller contact surface of the chain guide.
Furthermore, the vertical roller also comes into contact with the vertical roller contact surface of the chain guide and its direction is corrected while being pushed in the opposite direction to the driving means, and the conveyed object is attached to the attachment means and conveyed in the opposite direction to the driving means. be done. When the object to be transported is placed on the transport vehicle, the drive is stopped and the object to be transported is placed on the transport vehicle. The carriage is then moved to the processing machine where the object to be transported is installed, and the chain guides of the carriage and the chain guides of the intermediate carriage are aligned and fixed.

Then, the chain is driven in the pushing direction again to move the conveyed object to the processing machine.

When the object to be conveyed is removed from the processing machine and returned to the object storage area, the attachment means locks the object and pulls the conveyor. Then, the conveyor is pulled in the direction of the driving means, so the horizontal force roller corrects the direction of travel while contacting the horizontal roller contact surface of the chain guide, or even the vertical roller also contacting the vertical roller contact surface of the chain guide. While doing this, it is pulled toward the driving means,
The conveyed object attached to the attachment means is drawn toward the driving means. When the object to be transported is placed on the transport vehicle, the transport vehicle is moved to the object storage position and is again driven in the direction in which the driving means is pulled.

Then, the object to be transported is moved onto the mold storage area.
