Description

[Detailed description of the invention] (Industrial field of application) The present invention particularly relates to a sorting device that stops items whose distance from the reference line to the sorting surface is less than a predetermined distance and passes items that are greater than a predetermined distance. .

(Problems to be solved by conventional technology/devices) On the conveyor line, items with a distance (height, width, etc.) from the reference line to the sorting surface that is greater than a specified value are stopped, and items that are less than a specified value are allowed to pass. The sorting device can be easily established by simply fixing a stopper at a predetermined distance from the reference line, so it has been commonly used in the past. There are cases where it is desired to stop objects below a predetermined level and allow objects above a predetermined level to pass.

Automotive parts, such as hub drums for the front wheels and rear wheels of large trucks, have the same shape and diameter and only differ slightly in height, but are usually machined at the same location but assembled at different locations.

Therefore, it is difficult even for experienced workers to pick up hub drums for the front wheels and those for the rear wheels when they are sent from the processing site to the assembly site on a conveyor line. There is a risk of it being attached. When such incorrect assembly occurs, the later in the process it is discovered, the more effort and time it takes to replace and adjust it, and the greater the loss.

In this case, for example, when assembling objects with a predetermined height or more before the conveyor line, it is possible to use the conventional stopper described above; however, when assembling objects with a predetermined height before the conveyor line. Conventional technology cannot be applied.

On the other hand, Japanese Utility Model Application No. 58-191933 discloses a workpiece posture alignment device in which a differential case rolling on a guide rail is set on a jig with the flat surfaces of its rectangular parts aligned horizontally. However, this is done by providing a ski or counterweight lever with one end supported by a guide bar or hinge, with the guide bar or hinge side being slightly larger than the reference line, and the other end being the width of the flat surface from the reference line. Since the skis or counterweight lever have almost the same height as the width of the flat surface and do not have a stopping function, the skis or counterweight levers will pass through skis or counterweight levers that are the same height as the width of the flat surface. It is no different from conventional sorting equipment, as it only attempts to stop the object or change its position.

The present invention is designed to solve the above-mentioned problems and to provide a sorting device that reliably stops objects whose distance from the reference line to the sorting surface is less than a predetermined distance, and allows objects that are longer than a predetermined distance to pass through. It was issued.

(Means for Solving the Problems) The present invention for achieving the above object will be explained with reference to FIGS. 1 to 3 corresponding to the embodiments. 8a, a stop surface 8b perpendicular to the stop surface 8b, and a contact slope 8c continuing to the passing surface on the opposite side of the stop surface 8b. It is rotatably supported.

(Function) When the products to be sorted W ₁ and W ₂ move on the conveyor c described later and are about to pass through the main sorting device, the products to be sorted W ₁ move from the reference line (lower surface) to the sorting surface wa (upper surface). When the distance is smaller than the product to be sorted W ₂ , the upper end comes into contact with the stop surface 8b of the stopper 8 and is stopped. Further, the product to be sorted W ₂ first comes into contact with the abutment slope 8c of the stopper 8, and the stopper 8 is rotated upward around the pin bolt 9 described later, and as the product to be sorted W ₂ advances, its upper end surface comes into contact with the contact slope 8c. It comes into contact with the contact surface 8c (sometimes also called the passage surface 8a) and the end of the stop surface 8b, and passes with the stopper 8 raised. As a result, those with a large distance from the reference line (lower surface) to the sorting surface (upper surface) wa pass through, and those with a small distance are stopped and sorted.

(Embodiment) In the figure, reference numeral 1 denotes a support arm of the present device, whose lower end is attached to a conveyor C via a support stand 2, and whose upper end extends above the conveyor C.

Reference numeral 3 denotes a guide portion provided vertically at the tip of the support arm 1, and the support member 4 is formed to slide vertically on the circular portion. The upper part of the support member 4 is screwed together with an adjustment screw 6 which is attached to a fixing plate 5 fixed to the upper end of the guide part 3 so that it can be rotated to prevent it from coming off. 4 is configured to move up and down.

At the bottom of the support member 4, a mounting plate 7 is fixed on the side of the conveyor C, and a stopper 8 is attached with a hinge bolt 9 so as to be rotatable in the direction of movement of the products to be sorted W ₁ and W ₂ . .

The stopper 8 has a passing surface 8a on the lower surface, a stopping surface 8b perpendicular to this, and an abutment slope 8c that continues to the passing surface 8a on the opposite side of the stopping surface 8b, and is opposite to the hinge bolt 9. Stopper 8 on the side
A pin 10 fixed to the mounting plate 7 is inserted into the positioning/rotation regulating hole 8d. Thereby, the passage surface 8a of the stopper 8 is kept horizontal, and when the stopper 8 rotates, its rotation range is restricted.

After adjusting the position of the passing surface 8a by rotating the adjustment screw 6 to match the height of _W1 , which is the shorter of the products to be sorted (hub drums) _W1 and _W2 , the products are placed on the conveyor C. When the hub drums W ₁ and W ₂ are flown from upstream, the hub drum W ₁ having a low height advances without rotating the stopper 8 and comes into contact with the stop surface 8b and stops, so it is only necessary to take it out. In addition, the high hub drum W ₂ has a contact slope 8 of the stopper 8.
c and moves forward while rotating the stopper 8 upward, its upper surface contacts the contact slope 8c of the stopper 8, (sometimes the passing surface 8a) and the end of the stop surface 8b, and the stopper 8 is flipped up. Pass by. Therefore, the hub drums W ₁ and W ₂ are reliably sorted into those for the front wheels and those for the rear wheels.

(Application example) In the above embodiment, the stopper 8 is held in position using its own weight, but if the stopper 8 is configured to be pressed by a spring to hold the position, the stopper 8
The hinge bolt 9 can be set vertically, and the stopper can be rotated horizontally, and sorting can also be performed based on the difference in width direction.

(Effects) By configuring the present invention as described above, it is possible to pass objects whose distance from the reference line to the sorting surface is longer than a predetermined value, and to stop predetermined objects.
The above-mentioned predetermined item is useful, for example, when it is required before the assembly line, and losses due to the above-mentioned incorrect assembly can be avoided.

In addition, a stopper whose position can be adjusted using an adjustment screw has the effect of being able to handle items with different distances between the sorting surface and the reference line, and is not equipped with a position holding and rotation limiting mechanism. The position of the stopper can be reliably maintained, and since the range of rotation of the stopper is limited, the return of the sorted items after they have passed is also ensured.
