Description

DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) The present invention aims to continuously transport thin sheets such as veneer veneers by a conveyor, and to determine the grade and material of the thin sheets by visual inspection or other methods on the conveyor. , the thickness, dimensions, etc. are inspected and sorted, and the sorting signal is transmitted manually or automatically by operating a push pin, etc., and the sorting signal is transmitted to a memory circuit to determine the sorting type. It is applied to the sorting and stacking process of thin plates, which are separated and stacked separately at the stacking location directly below the transport relay comper, according to the
In the conventional sorting and stacking equipment for this kind of thin plates, every time the piles of thin plates sorted on the lift table at the same number of stacking locations as the types of sorting become full, the entire process is stopped and the sheets are taken out and emptied. The work efficiency was also low, as the work had to be started again after the previous work had been done, or alternatively, the number of depositing places that were multiples of the number of types to be sorted had to be prepared and these places had to be switched alternately each time. This was costly.

In addition, as in the article accumulating device described in Japanese Utility Model Publication No. 55-395, the first type discrimination section distinguishes the conveyance path for postcards and the conveyance path for envelopes, and this is further divided into the conveyance path for postcards and the conveyance path for envelopes. There is also an article accumulation device that uses a gate provided to control the sorting of articles such as mail accumulated in a pocket at the end to other pockets each time the number reaches a predetermined value. Needless to say, this requires a large installation space and huge equipment costs, and in this case, the number of transport paths and gates is doubled, resulting in problems such as an increased failure rate. Therefore, in order to eliminate the drawbacks of the conventional apparatus, the present invention provides one more deposition location than the number of types of thin plates to be sorted, so that one empty deposition location is always formed throughout the entire process. As the work progresses, as soon as the pile becomes full, the previous deposition work is automatically switched to the empty pile place, and the sequence is always repeated regardless of which place the pile becomes full. To provide a new thin plate sorting and depositing device that can efficiently and economically carry out continuous sorting and depositing work, including the work of taking out the pile, without stopping the whole process at all, using an empty depositing place prepared in The purpose is to (Structure of the Invention) As illustrated in an example of its implementation, the present invention inspects the grade, material, thickness, dimensions, etc. of a thin veneer plate 1 by visual inspection or other methods on a conveying compere 2a. At the same time as sorting, a sorting signal is transmitted manually or automatically by operating a push pin 3 or the like, and the sorting signal is transmitted to a storage circuit 4 consisting of a magnetic memory or the like to activate it. By this, conveyance release mechanisms 5a, 5b, 5c, 5d such as knock-down bars installed between the rows of the conveyance relay conveyor 2b consisting of a stabbing belt etc. installed in connection with the carry-in conveyor 2a, and the elevating table directly below. This method is applied to a thin plate sorting and stacking process in which the thin plates 1 are stacked separately according to the type of sorting at the stacking locations 7a, 7b, 7c, and 7d composed of the thin plates 6a, 6b, 6c, and 6d. In the invention, the thin plates 1 are deposited at four locations 7a, 7, which is one more than the number of sorting types of the thin plates 1, that is, one more than the number of sorting types, which is three in the illustrated case.
b, 7c, 7d, and the deposition locations 7a, 7b,
Empty detectors ga, 9b, 9c, 9d and full detectors 10a, 10b, 10c for stacking 8, each consisting of a limit switch, etc., for the upward and downward limits of lifting tables 6a, 6b, 6c, 6d, 7c and 7d, respectively. Erection 10d.

The fullness detectors 10a, 10b, 10c, and 10d become full as the stacks 8 on the lifting tables 6a, 6b, 6c, and 6d progress to form horizontal peaks, and the stacking location 7c becomes full, for example, as shown in the figure. A full signal is transmitted from the detector 10c, and as the stack 8 is taken out of the machine and emptied and the lifting tables 6a, 6b, 6c, 6d are reset to the initial stacking positions, for example, as shown in the figure. The empty signal is transmitted from the empty detector 9d as the stacking location 7d is reset. Furthermore, the full signal of the stack 8 transmitted from the full detector 10a, lob, 10c, 10d is transmitted to the stack 8 at the corresponding stack location 7a, 7b, 7c.
, 7d, and the empty detectors 9a, 9b, 9 are stopped.
the conveyance release mechanism 5a at the deposition location 7a, 7b, 7c, 7d from which the empty signal for the deposition 8 is transmitted from c, 9d;
5b, 5c, and 5d, the signal is transmitted to the deposition location switching circuit 11 consisting of a non-contact element, etc., which automatically switches the control circuit, and the switching control is performed, for example, as shown in the figure. Full detector 1 at deposition location 7c
The activation of the transport release mechanism 5c is stopped by the full signal of 0c, and the empty signal of the empty detector 9d at the stacking location 7d, which is formed at one location more than the number of sorting types of the thin plates 1 and has already been transmitted, is activated. The stacking place cutting circuit 11 is switched and controlled so as to activate the conveyance release mechanism 5d. Therefore, for example, a rotating drum such as a magnetic memory is connected to the rotating shaft of the conveyance comparer 2a or the conveyance relay comparer 2b so that it can be stored in synchronization with the conveyance speed of the conveyance comparer 2a and the conveyance relay comparer 2b in the deposition place switching circuit 11. Alternatively, a transducer or the like that sends a pulse signal proportional to the conveyance amount to a shift register or the like may be connected to the rotating shaft of the conveyance comparer 2a or conveyance relay comparer 2b, and the sorting signal is transmitted in proportion to the conveyance amount of the thin plate 1. By supporting the memory circuit 4 that synchronously stores and controlling the storage, for example, as shown in the figure, one empty deposition location 7d is always prepared, so that the deposition location 7c
As soon as the deposition area 8 becomes full, the previous memory-controlled deposition operation will be automatically switched to the empty deposition area 7d, and the deposition operation at the deposition area 7c will be stopped. If the pile 8 is taken out of the machine from the lift table 6c and emptied, and the lift table 6c is raised again to the position of the empty detector 9c and reset, this place becomes the next empty pile place 7c, and the pile 8 is emptied. No matter which deposition location becomes full, empty deposition locations can always be prepared one after the other. (Effects of the Invention) As described above, the present invention provides one more stacking locations 7a, 7b, 7c, and 7d than the number of types of thin plates 1 to be sorted, so that there is always one empty stacking location throughout the entire process. Locations 7a, 7b, 7c,
7d are formed in sequence, and as the work progresses, as soon as the deposit 8 becomes full, the previous deposition work is moved to the empty deposition locations 7a, 7b, 7c, and 7d. Sorting and stacking of thin plates formed by organically coupling empty detectors 9a, 9b, 9c, 9d, full detectors 10a, 10b, 10c, 10d, and stacking place cutting circuit 11 to a sorting signal storage circuit 4. Since it is a device, the installation space, equipment cost, and failure rate are significantly reduced, and the continuous sorting and stacking work, including the work of taking out the pile, can be carried out efficiently and economically without any interruption in the entire process. It was the first invention to be created, and it is an invention with extremely significant implementation effects.
