Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) In the present invention, the type is determined by measuring the length of an inverted product and the length of a stock item, for example, at the time of manufacturing an article and managing inventory of the article. The present invention relates to a shape discriminating device used for the like.

(Prior Art) A maker that manufactures an inverted article such as a bottle needs to count a quantity for each size of the bottle when performing quantity counting at the time of manufacture and inventory management. Especially in inventory management, products of various sizes may be stored in a mixed state, and the labor required to total the number of stored products for each type is very large. The development of an inventory management system that can do this is underway.

By the way, such an inventory management system suspends a plurality of storage shelves in which a plurality of inspection items are stored on a pair of endless chains, and drives the endless chains to move the storage shelves along a predetermined transport path. It is configured to be transported. Then, beer or the like stored in the storage shelf is detected by the photoelectric switch in the transport path, the shape is determined by a computer or the like, and the quantity is counted for each type of bottle.

The photoelectric switch used in such a system is composed of a combination of an infrared light projector and an infrared light receiver, and the length of the article in the transport direction of the article (high height) depends on the time during which the article to be inspected passes and the infrared light is shielded. Was measured and the quantity was calculated for each type.

(Problem to be Solved by the Invention) However, in the time shape discriminating apparatus, if the storage shelf vibrates due to the driving of the endless chain, the length (height) in the transport direction by the photoelectric switch cannot be accurately measured. was there.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a shape identification device capable of preventing a vibration at the time of detection and accurately identifying the shape of a conveyed article.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, in the shape identification device of the present invention, a pair of endless chains 1a and 1b conveyed along a predetermined conveyance path by a driving means, and The suspension shaft 6 disposed on the pair of endless chains 1a and 1b, the storage box 2 attached to the suspension shaft 6 and holding an inspection item, and the suspension shaft 6 provided on the pair of endless chains 1a and 1b A bearing member 7 rotatably held; shape detecting means 11 for detecting the shape of the article at a position where the test article stored in the storage box 2 is vertically conveyed; Rollers 9a, 9b are the endless chain pair 1a,
1b, a stabilizing member 8 provided in parallel with the two rollers
Guide members 10a, 1 provided only at portions of the transport path that pass through the shape detection means 11 so as to sandwich 9a, 9b.
0b, the storage box 2 conveyed by the pair of endless chains 1a, 1b is characterized in that its shape is detected by the shape detecting means 11 while vibration is prevented by the guide members 10a, 10b.

(Operation) In the shape discriminating apparatus of the present invention, the storage box in which the test articles are stored is guided perpendicularly to the transport direction by the stabilizing member sandwiched between the guide members in the transport path, and the vibration of the transport articles is guided by the guide members. Is prevented and the shape of the test article is accurately identified.

(Example) Hereinafter, an example of the present invention is described using a drawing.

FIG. 1 is a perspective view showing the configuration of an embodiment in which the present invention is applied to a beer shape identification device, FIG. 2 is a side view of a suspended portion of the shape identification device, and FIG. 3 is a rear view. .

As shown in the figure, a storage box 2 is suspended between a pair of endless chains 1a and 1b. The storage box 2 is provided with a plurality of storage pockets 4 for storing transported articles 3 such as canned beer and bottled beer. More endless chain pairs
The motors 1a and 1b are circulated at a constant speed by a driving device 5 using a motor.

On the back side of the storage box 2, a suspension shaft 6 is provided between the endless chains 1a and 1b. The endless chains 1a and 1b are provided with a bearing member 7 for rotatably holding the suspension shaft 6. Also, the suspension shaft 6
A stabilizing member 8 is fixedly provided on the suspension shaft 6 at the distal end of the suspension shaft 6. A roller is attached to the stabilizing member 8.
9a and 9b are provided, and can move up and down between guide rails 10a and 10b provided outside the endless chain 1a via rollers 9a and 9b. Vibrations of the rollers 9a and 9b are prevented by the vertically arranged guide rails 10a and 10b, and the vibration of the storage box 2 in which the inspection articles 3 are stored is eliminated.

Further, at a predetermined position of the transport path, the same number of shape detecting means 11, for example, photoelectric switches, as the number of the storage pockets 4 are provided, for detecting the inspection article 3 stored in the storage box 2 transported to that position. . The photoelectric switch 11 includes an infrared projector 11a that outputs an infrared beam, and an infrared projector 1a.
1a, and an infrared light receiver 11b for receiving infrared light from the infrared light projector 11a. When the infrared beam is blocked by the inspection article 3, a light-shielded signal is output from the infrared light receiver 11b. It has become.

Next, an operation of counting the inverted inspection articles 3 such as beer stored in the shape identification device thus configured for each type will be described.

The storage box 2 is circulated and transported by the pair of endless chains 1a and 1b, and sequentially passes through the photoelectric switch 11 at a position where it is transported vertically. At this time, because of the stabilizing member 8 sandwiched between the guide rails 10a and 10b, the storage box 2 is kept in a fixed posture in the inspection state without being affected by vibration for driving the endless chain pair 1a and 1b. And transported in the direction of arrow A shown in FIG. In this case, the guide member 10
Since the cuts are provided in the advancing portions of a and 10b, the rollers 9a and 9b can easily enter the guide members 10a and 10b.

Then, the infrared beam of the infrared projector 11a is projected on the inspection article 3 such as beer stored in the storage box 2 and the storage pocket 4 of the storage box 2. This infrared beam is blocked when the inspection article 3 passes, and the infrared receiver
11b outputs a light shielding signal. The shading time indicated by the shading signal and the speed of the storage box 2 circulated and conveyed by the endless chain pairs 1a and 1b are input to a computer (not shown), and the length of the inverted inspection article 3 such as beer in the conveying direction is reduced. It is calculated and the type is determined. Then, tallying is performed for each type.

Therefore, in the shape discriminating apparatus of this embodiment, the storage box 2 is provided with the stabilizing member 8 via the suspension shaft 6, and the stable member 8 is guided by the guide rails 10a and 10b. The endless chain pair 1a, 1b is not affected by vibration caused by driving or the like. For this reason, the length of the inspection article 3 can be accurately measured by the photoelectric switch 11, and the shape of the inspection article 3 can be accurately identified.

[Effects of the Invention] As described above, according to the shape identification device of the present invention, the storage box in which the inspection articles are stored is guided vertically by the stable member sandwiched between the guide members in the transport path in the transport direction. Therefore, the vibration of the storage box is eliminated, and the shape of the inspection article in the transportation process is accurately identified.
