Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is convenient for loading or stacking on a pallet when transporting packages to be transported such as cargo and other parcels and goods on a pallet in order of delivery destination. The present invention relates to a loading method performed under given conditions.

[0002]

2. Description of the Related Art Conventionally, in pallet transportation for loading cargoes including packages and cargoes on pallets, containers, etc., in the case of different types, an operator arranges articles individually while considering the loading position on the pallet one by one, If the first layer can be arranged in a plane from the lower layer and the first layer can be arranged in a plane, the second layer is sequentially layered in a layered manner, and even a skilled person requires a great deal of time and effort and fatigue. The degree was also extremely large. However, recently, in order to automatically carry out stowage work on pallets, there is a growing demand for freight transportation work by robotization, and the cargo flowing on the conveyor is grasped and palletized according to a predetermined pattern. It has also been attempted to automatically load the above items, but automation by robots is limited to cargos of the same shape and size, and they can be loaded on a single pallet such as a transportation system for reducing the number of different products. The larger the number of products to be attached, the more complicated the operation control becomes, and the more the robot has many products, the poorer the instantaneous force becomes and the workability becomes extremely poor. Is impossible or too time consuming to be totally practical. Therefore, a method of displaying the stowage position on the paper surface or the CRT screen can be considered as a method of transmitting the stowage position of the cargo to the worker, but in this method, the worker can see the paper surface or the CRT screen. However, while confirming, it was necessary to stack cargo from the lower layer to the upper layer one by one in order, and it was necessary to load cargo without shifting to the designated position, and the work was extremely difficult and not satisfactory.

[0003]

These conventional stacking methods are of a multi-product type because the layers are stacked in a plane and each layer is arranged on a plane and another product is placed on the layer to form the next layer in a plane. If the combination is made from the lower layers, the loading efficiency will be poor and the stability of the cargo after loading will be reduced. For example, when stacking multiple products on a flat surface, because other products are placed on top of products of different heights, unevenness is generated on the surface and becomes unstable, and it is inconvenient to create the next layer. There is a problem in that the flat surface that can be created when other products are placed on top of it becomes smaller, resulting in mountain-shaped loading, which significantly reduces the loading efficiency. The present invention eliminates these conventional drawbacks, makes it possible to stack loads appropriately and remarkably efficiently at a designated position on a pallet by a simple operation, simplifies the unloading work for each shipping destination, and improves work efficiency. It is an object of the present invention to provide a loading method capable of significantly improving

SUMMARY OF THE INVENTION The present invention, when loading parcels spanning a plurality of transportation destinations or different types of multi-type parcels on a pallet, transports them by deciding the cutting order in advance and carrying them by a conveyor. In the loading method of loading the parcels cut out on a loading surface such as a pallet, the same item product or the same group product is successively moved up and down along the same wall surface by moving the article transport conveyor or the pallet to load the article on the wall surface. It is a loading method characterized by stacking in a rod shape along the wall surface while making contact with each other, and sequentially placing the stacked pallets in a vertically stacked state.

[0005]

In the loading operation according to the present invention, the operator operates the transmission of the transport start signal of the transport conveyor 1 to determine the cutting order in advance and transport the loads 2 to be transported to the pallet 3
Stacked on top, but the cut out packages of the same group are sequentially struck against the wall surface, superposed and arranged in a bar shape and stacked on the pallet 3 from the back side to the front side. It is possible to efficiently load various loads onto the 3.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention will be described with reference to the example of FIG. By storing, when loading parcels or heterogeneous multi-kind parcels spread over a plurality of transportation destinations on the pallet 3, the cutting order is determined in advance and the conveyor 1 conveys the parcels, and the parcels cut out by the conveying conveyor 1 In the loading method for loading on the pallet 3 in 2, the articles 2 of the same item or the same group are moved up and down along the support plate 4 which is the same wall surface in order to move the article conveyor 1 or the pallet 3 sequentially, This is a loading method in which articles are stacked in a rod shape along the wall surface while being in contact with the wall surface, and are sequentially placed in a state of being collectively stacked on the pallet 3 in the vertical direction. In addition, the same group products cut out by the conveyor are the support plates 4 which are maintained in the horizontal or vertical state as the wall surface.
Place it on or abut it and place it in a bar shape,
Articles 2 lined up in a bar shape while pressing the inserted pieces 2 together from both ends with a support piece 5 such as a fork
It is preferable to support the side of the pallet with a vacuum or a clamp 6 and stack the pallet 3 from the back side to the front side. In this case, the support plate 4 is provided on an arm of a robot that can move up and down and swivel, and support pieces 5 and 5 are slidably provided at both ends of the support plate 4 to hold articles stacked in a rod shape. It is better to use one that does.

Further, as shown in FIG. 2, the article 2 cut out by the conveyor 1 such as a roller conveyor is raised on the conveyor and sequentially transferred with the bottom surface of the article in a vertical state, and the sheets are juxtaposed in parallel while being in contact with each other. The loading efficiency is to transfer the articles on the same wall surface, collect a predetermined number of the articles in a line and return or raise the bottom of each article 2 in a horizontal state, and load the articles on the pallet 3 from the back to the front. It can be greatly improved and is convenient. In this case, the same group of products cut out by the conveyer 1 are sequentially arranged in a row on the support plate 4 arranged horizontally, and after a predetermined number of polymerization arrangements, they are collectively held in a rod-like pressure. A loading method of vertically raising the support plate 4 and loading it on the pallet 3 is also effective, and it is preferable to use a means for holding the side surface with a vacuum or a clamp. In order to cause the article 2, for example, a star-shaped rotor is used to receive the article to be transferred, and then the article is rotated and inverted, and is fed out from the rotor by a feeding mechanism that moves between the rotors and conveyed onto the support plate 4. The support plate 4 can be reversed by lifting and moving it by a cylinder system or a robot mechanism.

Further, as shown in FIG. 3, the pallet 3 is
Of the stacking surface is held in advance in the vertical direction, a flow line is selected from the transport conveyor 1 by a sorting mechanism (not shown) on the stacking surface, and articles 2 coming in contact with the stacking surface are arranged in a rod shape to receive the receiving plate 3 ₁
The operation of placing the pallet on the top is repeated successively at the adjacent positions, and the pallet 3 in the vertical state is moved up and down together with the receiving surface 3 _{1 by the} lifter to stack the second and subsequent tiers, and then the articles are collectively palletized. A loading method that causes it to be horizontal is also effective. In this case, as the pallet 3,
A means is provided which is provided with a receiving plate 3 ₁ for receiving articles that is held in the horizontal direction, and the articles 2 are abutted against the pallet and the articles 2 flowing from the conveyor 1 are sequentially arranged on the receiving plate 3 ₁ in a rod shape. While it is convenient, and沿設was caused in place of the receiving plate 3 _first plate to the pallet 3, is transferred onto the pallet 3 causes the articles to cooperate in a horizontal direction of movement of the pallet 3 You can also Further, on the conveyor 1, it is considered that a flow direction regulation to a designated stacking position, for example, a sorting pusher, a combination with a lateral roller, or a channelizer is used. In addition, it is effective to lift the article from the side with a vacuum clamp and lift it together with the pallet. The flow of the articles 2 is arranged by using a pusher or a transfer mechanism in which rods or grippers that are distributed to each of the multiple transport conveyors 1 are moved in the width direction to be fed, and further pushed onto the receiving plate 3 _1. Things are also selected and used.

[0009] Further, instead of the pallet, it is possible to utilize by utilizing a container, a loading platform or the like, and it is also effective to carry out a combination stowage operation using stowage software. After inputting the quantity order data and adding the product master, such as dimensions, weight, volume, shape, etc., and determining the unit unit by total weight, total area, and number of recipients, weight group, bottom stacking, side stacking, housing Determine the product ranking from the flag that can be seen in the area and instruct the product supply line, arrange the units in each cutting order in the reverse order of the destination, and the stacking rule, that is, the stacking method, for example, the maximum stacking height, Calculate the loading position and loading direction in accordance with conditions such as grouping of similar-sized products (things with similar dimensions may be stacked on top) and prohibited items (prohibition of heavy items on top of light items) Then And determining flow in a short side direction or the flow in the side direction can be conveyed and stowage of the product to be loading. In this case, the packages should be transported in order of decreasing weight, and those with a large bottom area of the packages within the same weight group or the bottom area and the living area should be compared and the larger area should be prioritized to determine the cutting order. It is considered that the cargo is transported or loaded on the pallet for each same transportation destination, and that the cargo transportation is performed by dividing the cargo for each transportation destination.
