Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cap-shaped work aligning and conveying device for conveying cap-shaped members in a line with their heads aligned.
[0002]
[Prior art]
As shown in FIG. 3, the cap-shaped workpiece 10 having a heavier head is conveyed in a line from the parts feeder in an irregular state, and is aligned so that the head is at the end at the end of the conveying path to form a straight feeder. Conventionally, the means shown in FIGS. 4 and 5 has been considered as the supplying means.
That is, an OK passage 12 is formed by providing a concave portion 11 at the end of the parts feeder 10, and an NG work passage 13 is provided on the same plane at a predetermined interval L. When the cap-shaped work W tries to advance on the concave portion 11 at the end of the parts feeder 10 with the head first, the head is heavy, so that it tilts downward as shown in FIG. When the work W 'having the lower part comes first, it moves over the recess 11 to the NG passage 13 without leaning downward as shown in FIG. However, even the work W with the head first moves on to the NG passage 13 without leaning downward, and the work W 'with the lower part also leans downward at the recess 11 and enters the OK passage 12. There was something.
[0003]
[Problems to be solved by the invention]
In the above prior art, since the alignment is performed using the center of gravity of the cap-shaped work, the adjustment of the size of the concave portion and the speed of the parts feeder is delicate and cannot be adjusted 100% accurately. There is a problem that an automatic device for eliminating the defective work is required, and the device is complicated and expensive.
[0004]
[Means for Solving the Problems]
An object of the present invention is to solve the above-described problems, and the protrusion is directed in a direction in which the cap-shaped member is conveyed to an end of a conveyance path in which the cap-shaped members are conveyed in a line in an irregular front and rear direction. A plurality of protrusions into which a cap- shaped member can be inserted are provided on the outer periphery of the disk, and the cap-shaped member is rotatably conveyed while being inserted into the protrusion .
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described in detail with reference to FIGS.
Reference numeral 1 denotes a well-known parts feeder that forwardly conveys the spiral path with vibrations of the spiral path being irregular in front and rear due to vibration. Reference numeral 2 denotes a work reversing plate disposed at an end of the parts feeder 1 at a right angle to the conveyance path, and has protrusions 2a formed at regular intervals on the outer periphery of the disk. Reference numeral 3 denotes a speed control motor that rotates the work reversing plate 2 at a predetermined speed, and reference numeral 4 denotes a linear feeder that leads to the next step.
[0006]
Next, the operation will be described.
A work W in a cap shape is fed to the parts feeder 1 in a non-uniform manner. Since the work reversing plate 2 is rotated in accordance with the traveling speed of the work W, the work W having the lower part first fits into the projection 2a of the work reversing plate 2 and turns over and falls onto the linear feeder 4. The work with the head first falls down without fitting into the projection 2a. Therefore, only the work whose head is directed first is sent to the linear feeder 4.
[0007]
【The invention's effect】
According to the present invention, there is provided a protrusion capable of inserting a cap- shaped member whose projection is oriented in a direction in which the cap-shaped member is conveyed to an end portion of a conveyance path in which the cap-shaped members are conveyed in a line in a state in which the cap-shaped members are not aligned. Since the cap-shaped member having a plurality of protruding portions on the outer periphery of the disk is rotatably conveyed while being inserted into the protruding portion, the cap-shaped work can be conveyed with approximately 100% uniformity. This has the advantage that it becomes unnecessary and the whole apparatus is simple and inexpensive.
