Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting device used when a cylindrical molded product made of, for example, a resin, which is punched out from a tableting machine, is aligned by an aligning machine and packed in a box.

[0002]

2. Description of the Related Art Generally, when aligning molded products (hereinafter referred to as works), it is necessary to sort the works before the aligning machine. The sorting device for performing the above sorting operation has a star shape having a concave portion for engaging the workpiece corresponding to the diameter of the workpiece on the periphery, and rotates a rotating body called a star wheel to send the workpiece to the next process. I am trying.

The number of workpieces sent to the next process is counted by counting the workpieces mounted on the star wheel and the star-shaped plate attached to the star wheel with respective proximity sensors. That is, as long as the detection outputs of both sensors match, the number of works sent out by the star wheel and the star-shaped plate is the same, and the operation of the sorting device is continued assuming that the sorting operation is performed accurately. It

In the above sorting apparatus, the workpieces sent out by the star wheel and the star-shaped plate are sequentially sorted into 1 to N rows.

On the other hand, the customer's requirements for the alignment packaging process are becoming stricter. In other words, in order to cope with the abnormal labor shortage in recent years, automation of packaging work is required, but not only mere automation, (1) Not only labor saving by automation, but also delivery time for quantitative problems From the point of view of shortening, the demanding requirements of customers must be dealt with by automation.

(2) At the customer to whom the work has been delivered,
In order to start processing by unpacking the delivered package and immediately putting it on an automatic machine, it is necessary to ensure the number of workpieces and the alignment state on the shipping side.

(3) No defects such as cracks and chips of the work.

Etc. are required.

[0009]

In the conventional sorting device having the above-mentioned structure, the number of works sent out by the star wheel or the like can be grasped as long as the sorting device is operating smoothly, but it is out of order. Or, if the alignment machine or the like is stopped for maintenance, it becomes uncertain to grasp the number. Therefore, it is necessary to visually confirm the number of sheets to be sent out after the suspension.

These problems prevent the requirement (2) from being met. Further, in the above-mentioned conventional sorting apparatus, (a) it is not possible to grasp the number of works between the sorting apparatus and the aligning machine gate in the next process.

(B) As related to the previous item (a), when trying to initialize after a temporary stop, the workpieces in the gate are packed together, and the alignment state and the number of workpieces are changed. .

(C) When the packing and packing of the work in the gate described in the above item (b) occurs, the work is caught at the aligned portion unless the interlock is taken.

(D) In the conventional aligning machine, since counting is performed in the aligning section, there is a risk that a hand may be involved when correcting the number.

There are problems such as

The present invention has been made based on the above-mentioned circumstances, and it is possible to accurately grasp the number of delivered work pieces and to distribute the work pieces in a cylindrical molded product aligning machine in which the work pieces are not caught. Provide a device.

[0016]

According to another aspect of the present invention, there is provided a sorting apparatus for a cylindrical molded product aligning machine, wherein the cylindrical molded product supplied from the preceding stage is sorted into a plurality of gates. A star wheel that gives a driving force for aligning the molded products, a guide that guides the cylindrical molded product that has been given the driving force to the gate, and counts the driven cylindrical molded products at the guide outlet. A sensor,
A control device for registering the movement amount of the sensor provided at the guide and the outlet according to the diameter of the cylindrical molded product and the gate row number into which the cylindrical molded product is fed.

[0017]

In the sorting device of the cylindrical molded product aligning machine of the present invention having the above-mentioned structure, the cylindrical molded products come into the star wheel in a row. The star wheel applies a driving force toward the gate, and the control device moves the guide and the sensor as much as necessary according to the gate row number and the diameter of the cylindrical molded product, and each counts without causing a counting error. The gates can be counted and aligned.

In FIG. 3, the star wheel 11 is mounted on a star wheel mounting plate 19, and a part of the star wheel 11 projects outside the immediately preceding guide 6a. An encoder 20 and a cross roller guide 21 are provided on the star wheel mounting plate 19, respectively. Further, the star wheel mounting plate 19 is provided with a motor 22 for finely adjusting the position of the first sensor 8. The star wheel 11 is set to be replaced each time in accordance with the diameter of the work to be handled.

In the above embodiment having the above-mentioned structure, the work 1
The distribution of 8 is performed as follows. First, the control device 1
In 5, the amount of movement of the first sensor 8 is registered according to the row to which the work of the gate 7 is to be fed in the next step and the diameter of the work to be fed. The specific examples are shown in Table 1 below. However, the sensor movement amount is indicated by the count amount.

[0023]

[Table 1] The sorting device in the aligning machine for cylindrical molded articles of the present invention having the above-described configuration operates as follows. That is, when the apparatus is started up, the diameter of the workpiece currently handled by the control apparatus 15,
The number of lines arranged for each gate row number is set.

Here, the rotation of the star wheel 11 starts the feeding of the work from the previous stage. Now, for example, if the work of φ30 is aligned with the gate row number 1, the movement amount of the first sensor 8 and the guide 6a immediately before the star wheel is 0, and the gate row number 1 is reached when the set number coefficient of the first sensor 8 is completed. It is possible to confirm the completion of the alignment of the predetermined number. Next, the alignment to the gate row number 2 is started. At this time, the first sensor 8 and the guide 6a immediately before the star wheel are moved by the count amount 60. This first sensor 8
By the completion of the set number coefficient of, it is confirmed that the number of gates arranged in the gate row number 2 is exceeded. Below, gate row numbers 3 and 4
Even when the alignment is started, the first sensor 8 and the guide 6a immediately before the star wheel are moved by the count amounts 80 and 100, respectively.

By moving the first sensor 8 and the guide 6a immediately before the star wheel, even when the guide 6a immediately before the star wheel is rotated and directed to the gate row numbers 2 to 4, counting is performed. No error will occur.
Moreover, the number of workpieces existing in the apparatus can be always grasped by counting the first sensor 8 and the third sensor 14, and it is not necessary to visually confirm the number.

When the types (diameters) of works to be handled differ as described above, adjustments including attachment / detachment, replacement, etc. are performed on the star wheels, sensors, etc. to handle them.

[0027]

As is apparent from the above, according to the sorting apparatus in the cylindrical molded product aligning machine of the present invention, the number of works in the line can be grasped without the need for visual confirmation by the operator. Since the number of pieces can be accurately boxed and there is no fear of packing different types of products in an aligned box, accurate boxing can be performed, so that the customer can unpack and immediately start work.
