Abstract

PURPOSE:To prevent collapsing, stumbling or the like of cargoes when a tall load pallet is conveyed between the points having a height difference between them so as to perform stable conveying by arranging an auxiliary conveying device, which can be inclined, in the terminal end of a main conveying device. CONSTITUTION:A tall load pallet A is conveyed from a parallel conveyor 1 to a parallelly set auxiliary conveying device 2 and is engagingly stopped by a stopper 5. The auxiliary conveying device 2, on which the tall load pallet A is placed, is adjusted to the inclination of a downwardly inclined main conveying device 3 by regulating a stroke of a cylinder 4. Then, the tall load pallet A is transferred from the auxiliary conveying device 2 to the main conveying device 3, which has an equal inclination to that of the auxiliary conveying device 2, by pushing down the stopper 5, and subsequently, conveyed as it is by means of the main conveying device 3, and transferred to the parallel conveyor in the terminal end of the main conveying device 3 so as to be conveyed into a target place.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for stably and continuously transporting a high-load pallet on an inclined surface.

[0002]

2. Description of the Related Art Conventionally, a method for transporting a high-load pallet between points having different heights without collapsing the load is not to transfer the points along an inclined surface which directly connects the points but to connect a horizontal portion between the points. It is divided into a lifting part and a horizontal part is carried by a belt conveyor, a chain conveyor, etc., and the lifting part is carried by using a lifting device such as an elevator or lifter as shown in FIGS. 3 (a), (b) and (c). Are being transported. In this way, the transport unit is divided into the horizontal transport unit and the vertical transport unit to avoid the collapse of the pallet at the branch point where the horizontal transport moves to the vertical transport and the pallet tripping. However, in this method, as compared with the method of linearly transporting the transported object to the destination, in (a) and (b), ascending and descending must be repeated for each pallet, and in (c), 1 is required. It was necessary to wait until batches of pallets were gathered, which was inefficient and took a long time to transfer.

[0003]

SUMMARY OF THE INVENTION The present invention is an efficient and short-term transfer of a high-load pallet between points having different altitudes as described above, and also causes the pallet to collapse and the pallet to trip. An object of the present invention is to provide a method for transporting a high-load pallet on an inclined surface that prevents the above, and an apparatus used for the method.

[0004]

SUMMARY OF THE INVENTION The above-mentioned problems are solved by the present invention, in which a main transporting device having a variable inclination angle connecting a starting point and a finishing point of a conveyed object having different heights and a terminal of the main conveyor are installed. It is composed of an auxiliary transport device whose tilt angle can be changed, and first transports the transported product to the auxiliary transport device that is set horizontally, and the auxiliary transport device has the same inclination as the main transport device to transport the transported product auxiliary. The problem can be solved by using an inclined surface conveyed object conveying device which is characterized in that the conveyed object is transferred from the apparatus to the main conveyed apparatus and the conveyed object is conveyed to the conveyed object end point by the main conveying apparatus.

In the present invention, as the main carrier device and the auxiliary carrier device, it is possible to use a tiltable carrier device such as a chain conveyor, a belt conveyor or a roller conveyor. In the present invention, the inclinations of the main carrier device and the auxiliary carrier device are made to coincide with each other, and the transported object is transferred from the auxiliary carrier device to the main carrier device without any step. It is preferable to install the auxiliary transfer device at both ends of the main transfer device in order to prevent collapse of the high load pallet,
Considering the packing style, height, packaging condition of high-load pallets, and conditions such as when transporting from high places to low places, and from low places to high places, even if installed only at one end, the load of high-load pallets will collapse sufficiently. It is effective for prevention. The tilt angle of the auxiliary carrier can be adjusted by adjusting one end of the auxiliary carrier with a cylinder at the other end and adjusting the stroke of the cylinder.
Also, the inclination angle is about 5 degrees when the main conveyor is a chain, but it can be inclined up to several tens of degrees by adding attachment etc. to the chain, depending on the shape and height of the conveyed object. Is.

[0006]

According to the present invention, since the auxiliary conveying device which can be tilted is provided at the end of the main conveying device, the conveyed product can be gradually inclined and conveyed from the starting point of the conveyed product to the main conveying device without any step. Is shortened.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a conceptual view of the device of the present invention, (a) is a front view and (b) is a plan view. 2A and 2B are views for explaining the relationship between the auxiliary transporting device and the main transporting device of the present invention and for explaining the actual transporting state. FIG. 2A is a plan view and FIG. 2B is a front view. As shown in Fig. 1, high load pallet A (height 2260mm; width 1130
mm, length 1440 mm) is the auxiliary conveyor device (roller conveyor) 2 (width 580 mm; length) set horizontally from the horizontal conveyor 1.
It is transported to 1200 mm) and locked by the stopper 5. The main conveyor (inclined chain conveyor) 3 (width 950 mm) in which the auxiliary conveyor 2 on which the high-load pallet A is placed is tilted downward by 5 degrees by adjusting the stroke of the cylinder 4.
; Adjust the tilt angle to 5750mm). Next, the high-load pallet A is moved from the auxiliary transport device 2 to the main transport device 3 having the same inclination by tilting the stopper 5, is transported by the main transport device as it is, and is transported to the horizontal conveyor at the end of the main transport device and is transferred to the truck. Be delivered to.

[0008]

As described above, the present invention has the following effects by providing the auxiliary carrier device whose tilt angle can be changed at the end of the main carrier device whose tilt angle can be changed. When carrying, there is no movement of up and down,
It is not necessary to wait until the pallets for one batch are gathered, and since continuous transportation is possible, the transportation time is shortened and the transportation capacity is improved. Since the transported objects can be smoothly transferred between points having different altitudes, the collapse of the transported objects and the tripping can be eliminated, and stable transportation can be achieved, thus improving the transportation efficiency.
