Abstract

PURPOSE:To allow loading to be resumed without hindrance even in the case of the operation of a device being stopped due to power failure or some other trouble during loading operation by reading the weight value, measured by a weight detector, into a control device so as to be computed to obtain the number of loads, and determining a position of loading the load onto pallet on the basis of the computed number of loads. CONSTITUTION:There is provided a weight detector 2 for measuring the whole weight of a pallet placed in a loading position. The whole weight of the pallet measured by the weight detector 2 is read into a control device 3 so as to be computed to obtain the number of loads. The moving position of a load holder onto the pallet is controlled on the basis of this number of loads. As a result, loading can be resumed without hindrance even in the case of the operation of a device being stopped due to power failure or some other trouble during loading operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet loading device for loading cargo such as paddy bags and cardboard cases on a pallet.

[0002]

2. Description of the Related Art Pallet loading devices are described in, for example, Japanese Patent Publication No. 62-47772 and Japanese Patent Publication No. 57-151533. These pallet loading devices are configured to stack loads suspended one by one with a load suspending tool according to a predetermined pattern while sequentially changing the stacking position so as not to create a wasteful space on the pallet.

[0003]

In the conventional pallet loading apparatus, the pallet loading position is determined according to a program in the control unit. For this reason, if a power failure occurs during loading or the loading status is manually corrected during loading, the program will be disturbed and it will take time and effort to return to the normal state. Therefore, in the present invention, the number of packages already loaded on the pallet is calculated by the following configuration, so that even if the program is interrupted, it can be immediately returned to the continuous state when restarted.

[0004]

In a pallet loading apparatus for moving an article holder 13 on which a load is suspended onto a pallet P to load the load onto the pallet P in accordance with a predetermined stacking pattern, a loading portion for the pallet P is placed. 1 is provided with a weight detector 2, and the weight value W measured by the weight detector 2 is read into the control device 3 to calculate the load number M, and the load number M
It is configured to control the moving position of the article holder 13 based on the above.

[0005]

The weight value W measured by the weight detector 2 is read into the control device 3 to calculate the load number M, and the position for loading the load on the pallet P is determined based on this value. By accurately determining the number of loads already loaded on the pallet P, even if a trouble occurs during the loading and the work is interrupted, the stacked state is not disturbed. Incidentally, if the load number M calculated from the weight value W measured by the weight detector 2 is compared with the separately counted load number N and the operating state is checked, a load error can be known. Quickly handle repairs and adjustments.

[0006]

EXAMPLE An example of the present invention will be described below. 3 and 4 show a pallet supply device 4 that stocks the pallets P and supplies them one by one, and a loading device 5 that stacks loads on the pallets P. The pallet feeder 4 is
When a large number of pallets P are stacked and the handle 6 is turned, the pallets P drop one by one and slide on the lower inclined roller conveyor 7 to be supplied below the loading device 5.

In the loading device 5, columns 9 and 10 are erected on the left and right, and horizontal guide rails 11 are mounted on the columns 9 and 10 so as to move up and down, and a moving frame 12 is horizontally mounted on the horizontal guide rails 11. An article holder 13 is attached to the moving frame 12 so as to move back and forth.
A pallet transfer device 14 is provided between the left and right columns 9 and 10, and a pallet P supplied from the pallet supply device 4 is provided.
Is supplied to a predetermined position below the article holder 13. The pallet transfer device 14 has chains 16 and 16 stretched on the left and right of a frame body 15, and receives and transfers the lower surfaces of the pallet P.

A weight detector 2 is provided at the center on the left and right sides of the pallet carrier 14 so that the total weight W can be measured by receiving the center of the pallet P which has been conveyed and has reached a predetermined position. The load to be stacked on the pallet P is one of the columns 9
Side to the front side, the article holder 13 moves to this position to suspend the load, and moves to a predetermined position according to the stacking pattern on the pallet P to stack without wasteful space. Become.

Next, the control state of the article holder 13 will be described with reference to FIGS. 1 and 2. First, the load number setting unit 17 sets the number G of loads to be stacked on the pallet P, and the load weight setting unit 18 inputs the average weight R of one load. After that, the pallet P is supplied and carried into a predetermined position of the loading device 5. Here, the weight detector 2 detects the weight PW of the pallet P and stores it in the control device 3.

Next, the number of loads M is calculated from the total weight W measured by the weight detector 2 by the following formula, and the calculated number of loads M and the number of loads N counted up from the beginning are compared, and the load is surely loaded. Check if is done. M = (W-PW) / R (M is rounded to an integer.) Since the total weight W is the same as the pallet weight PW at the beginning, the number of loads M is zero and the number of counts N is also zero. is there.

The control device 3 controls the moving position of the article holder 13 by designating the placement position of the next load on the pallet P from the load number M calculated above, and the loading state indicator 19 Display the stacking status on. If the calculated load M is not the same as the count N, the article holder 13
Judges that it has failed to suspend the luggage, displays it on the trouble indicator 20, and stops the movement of the article holder 13.

When the loading progresses and the loading number N reaches the designated loading number G, the movement of the article holder 13 is temporarily stopped to carry out the loaded pallet P and supply the empty pallet P. The article holder 13 is again moved to continue the loading work.
