Description

Description: TECHNICAL FIELD The present invention relates to an apparatus for supplying a work to a rotating working drum and packing a product automatically assembled or processed on the working drum in a box.

(Prior Art) Conventionally, as shown in FIG. 3, in an automatic assembly machine or automatic processing machine in which a work 2 is supplied to a rotating working drum 1 and products are continuously completed on the working drum 1, If it is necessary to pack a fixed number of finished products in a box, store the products in different boxes for a certain period of time and manually repack them in a box, or use a machine such as a parts feeder. After aligning the products and counting the numbers, they were packed in a box manually or by pick and place.

(Problems to be Solved by the Invention) However, these means do not directly pack the products from the machine, but require one more process. Depending on the workpiece, a large parts feeder is also required, and the system becomes large, and when the box is filled with products and the box needs to be replaced, the machine must be stopped temporarily, which reduces the efficiency of box packing. There was a point.

(Means for Solving Problems) An object of the present invention is to solve the above problems, and a working drum provided with grooves on the outer periphery at which work pieces are inserted at equal intervals, and a groove interval of the working drum. A discharge drum having an odd number of grooves into which work is inserted is arranged in the vicinity, and the discharge drum has an intermittent rotation mechanism that rotates several pitches while the work drum rotates one pitch. Further, a count sensor and a shutter device are provided, and the shutter is closed when a predetermined number of works are counted.

Hereinafter, a specific description will be given based on the illustrated embodiment. 1
Is a work drum that rotates intermittently and is a work 2 at regular intervals on the outer circumference.
A groove 3 is formed therein for receiving. Numeral 4 is a discharge drum which is arranged close to the working drum 1 and rotates intermittently. An odd number of grooves 5 having the same pitch as the grooves 3 of the working drum 1 are formed on the outer circumference, and the discharging drum 4 has two pitches while the working drum 1 is rotated by a pitch. It is synchronized to rotate. Therefore, the works 2 that have entered the grooves 3 of the working drum 1 enter every other groove 5 of the discharge drum 4. A fixed guide 6 is arranged on the outer circumference of the discharge drum 4, and a work transfer section A and a work discharge section B are cut out. Solenoid 7 in work discharge part B
A shutter 8, a chute 9, and a count sensor 10 which are opened and closed by the are provided.

Next, the operation will be described. The work pieces 2 sequentially entering the grooves 3 of the work drum 1 become products by being subjected to assembly work or processing work during intermittent rotation. Then every other groove 5 of the discharge drum 4 enters. The product 2'in the groove 5 is intermittently rotated along the fixed guide 6, the number of the product 2'is counted by the count sensor 10, the shutter 8 is opened by the solenoid 7, and the product 2'is put into the product box by the chute 9. Box up to a fixed number. When the product box is full and the product box needs to be replaced, the shutter 7 is closed by the solenoid 7.
Therefore, the product 2 ′ transferred from the work transfer section A to the groove 5 of the discharge drum 4 is not discharged to the chute 9 but reaches the transfer section A by further rotating half a turn. Since the groove 5 is an odd number, the groove 5 containing the product 2'does not coincide with the groove 3 of the working drum 1 and the empty groove 5 coincides, so that the discharging drum 4 is further 1
The shutter 8 can be closed during rotation. Replace the product box within this time, then shutter 8
Open and count the product 2'with the count sensor 10 and pack the product 2'in a new product box.

(Effect) According to the present invention, the working drum having grooves on the outer periphery where work is inserted at equal intervals, and the discharge drum provided with an odd number of grooves for receiving work, which have the same groove spacing as the working drum, are arranged close to each other. ,
The work drum has an intermittent rotation mechanism such that the work drum rotates one pitch for several pitches, and a count sensor and a shutter device are provided at predetermined positions on the outer circumference of the work drum to count a predetermined number of works. Since the shutter is closed occasionally, the parts feeder is not required and the work drum can be continuously packed in the box, and even when the product box is full, the box can be packed without stopping the work drum.

Claims (1)

[Claims] 1. A working drum, in which a working drum having grooves at which work pieces are inserted at equal intervals on the outer periphery and a discharge drum having an odd number of grooves at which work pieces are inserted are arranged in proximity to each other. Has an intermittent rotation mechanism such that the discharge drum rotates several pitches while rotating 1 pitch, and a count sensor and a shutter device are provided at a predetermined position on the outer circumference of the discharge drum.
