Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a parts selection device for classifying parts such as bolts by type.

[0002]

[Prior Art]

 A conventional component sorting apparatus will be described with reference to FIG. FIG. 1 is a plan view of the component sorting apparatus 1, in which circular rollers 2 are arranged side by side and the intervals between the rollers 2 are arranged so as to expand rearward (to the right in the figure). .. Further, the roller 2 is configured such that the upper portion of the roller 2 is rotated from the inner side to the outer side by a driving mechanism (not shown).

On the other hand, the end of the conveyor 3 is arranged on the upper surface of the front part of the roller 2, and the conveyor 3 is configured so that various parts can be conveyed and placed on the upper surface between the rollers 2. There is. Thus, when the roller 2 is rotated and the parts such as bolts are conveyed by the belt conveyor 3, the parts move backward and drop when the width of each part and the distance between the rollers 2 match. ..

Therefore, since parts having different widths, sizes, and the like have different drop positions, it is possible to sort the parts according to the type of the parts.

[0005]

[Problems to be solved by the device]

 In the above-described conventional component sorting apparatus, one roller is obliquely installed so that the other roller expands in the traveling direction of the component. That is, the distance between the rollers is widened in a taper shape, and when the distance is equal to or larger than the width, size, etc. of the parts, the parts are dropped and can be selected. ing.

However, since the distance between the rollers is gradually increased, the attitude of the parts moving on the rollers is not stable, and even the same parts, the drop positions are not constant and the parts are reliably selected. I couldn't do it. Further, as the number of parts to be selected increases, the length of the roller increases, which requires a large installation space, which is very inconvenient. Therefore, there is a technical problem to be solved in order to surely select the parts and also to reduce the installation space of the device, and the present invention aims to solve the problem. ..

[0007]

[Means for Solving the Problems]

 This invention has been proposed to achieve the above-mentioned object. Cylindrical rotation-independent rollers are arranged side by side in parallel, and a pair of left and right rollers are arranged in a plurality of upper and lower stages. An object of the present invention is to provide a parts selecting device characterized in that the rollers are inclined downward from the base toward the tip, and the intervals between the rollers of the respective stages are sequentially reduced from the upper stage to the lower side.

[0008]

[Action]

 In this invention, since a pair of rollers facing each other on the left and right are arranged in parallel, each of the parts to be selected is stably supported by a predetermined number of rollers having an interval smaller than the width of the part. Be transported to. Therefore, it is possible to reliably select various parts. Further, since the pair of right and left rollers are arranged in the upper and lower stages, the installation space of the sorting apparatus can be reduced.

【Example】

 An embodiment of the present invention will be described below in detail with reference to the attached FIGS. 1 and 2. In the figure, reference numeral 10 is a component sorting device, and as shown in FIG. 1, the component sorting device 10 is configured to sort components such as bolts supplied to a hopper 11 into a sorting box 12. At the central portion of the component sorting apparatus 10, a pair of rollers 13 facing each other are arranged in upper and lower four stages. As shown in FIG. 2, the rollers 13 are arranged side by side in parallel, and the distance between the left and right rollers 13 is sequentially reduced from the upper stage to the lower stage. The interval between the rollers 13 is set according to each component to be selected.

The roller 13 is rotatably mounted and rotated by a drive mechanism (not shown). The rotation is such that the upper part of the roller 13 rotates from the inside toward the outside. Further, each roller 13 is provided obliquely downward toward the rear (left in FIG. 1). On the other hand, a supply conveyor 14 is provided between the hopper 11 and the roller 13 so that the components thrown into the hopper 11 can be dropped onto the upper surface of the tip of the roller 13 in the upper stage.

Further, a discharge conveyor 15 is arranged below the rear end of the rollers 13 from the uppermost stage to the third stage and below the lowermost roller 13 and is conveyed by the rollers 13 of each stage. The product is configured to be dropped on the sorting box 12. In the figure, reference numeral 16 is a support frame, and 17 is a guide plate for surely conveying the parts to be selected. Thus, when the parts are selected, the roller 13 is rotated and the supply conveyor 14 and the discharge conveyor 15 are driven. Then, when the parts to be sorted are put into the hopper 11, the parts are dropped by the supply conveyor 14 on the upper surface between the uppermost rollers 13. The parts dropped on the upper surface of the roller 13 are conveyed between the rollers 13 in the steps having a distance smaller than each width. Further, during the transportation, since the respective parts are moved to the fixed postures by the rotation of the roller 13, it is possible to surely classify the various parts between the rollers 13 of a predetermined stage.

Then, due to the rotation and inclination of the roller 13, the parts are dropped from the rear end of the roller 13 onto the discharge conveyor 15, and the discharge conveyor 15 conveys the selected parts to a predetermined selection box 12. .. Therefore, the parts supplied to the hopper 11 are sorted and conveyed to the sorting box. It should be noted that the present invention should not be limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the invention, and the scope of the invention is the modifications. Of course.

[0013]

As described in detail in the above-mentioned embodiment, the present invention forms a pair of rotatable left and right rollers in a plurality of stages, and arranges the rollers in parallel to sort parts. Configured. Therefore, the parts to be sorted are stably placed in a stable posture and dropped onto the rollers in predetermined stages, so that accurate sorting can be realized. Further, since the rollers are configured in a plurality of stages, the installation space for the component selection device can be made small, so that the line of a factory or the like can be efficiently set, which is a remarkable effect.
