Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a component supply device for supplying cylindrical, spherical, etc. components.

As a component feeding device for cylindrical or spherical components 1 as shown in FIG. Therefore, there is a system that transfers and supplies in a line.

However, in conventional devices of this type, the upper surface of the inclined chute 20 is formed into a V groove 3 or a U groove 4 as shown in FIG. If the part 1 gets caught near the exit of the chute 2, or if the parts 1 are full on the parts storage side and stacked on the inclined chute 2, and the outlet of the inclined chute 2 is clogged by the weight of the parts 1. etc. Therefore, a component removal device is attached near the exit of the inclined chute 2, and when a component 1 becomes clogged, the component 1 on the inclined chute 2 must be dropped using this device. It was necessary to provide a fullness detector to detect when the component 1 became full and to stop the vertical movement of the blade. In view of the above-mentioned conventional problems, the present invention is capable of self-correcting the catching of parts on the inclined chute without using any special additional equipment, and also allows the parts to remain on the inclined chute even when the parts are full. To provide an inexpensive and compact parts supply device in which parts are returned to a parts storage part by natural fall.

A second object of the present invention is to arrange a large number of hoppers as described above and use a Yajirobee type drive system to absorb the weight balance of the blades with a lever, thereby reducing the driving force. .

Hereinafter, illustrated embodiments of the present invention will be described in detail.

First, the basic configuration of this device will be explained. 3 to 5, 5 is a base plate, 6 is an outer frame attached to this base plate 5, and the inside of the outer frame 6 is the part 1.
This is a parts storage section 7 that stores. Reference numeral 8 denotes an inclined chute, which is attached to the base plate 5 at an inclination angle such that the component 1 is dropped downward by natural fall, and a cylindrical external chute 9 is connected to its tip.

Reference numeral 10 denotes a blade that transfers and supplies the parts 1 from the parts storage section 7 onto the inclined chute 8, and is slidable up and down along the inclined chute 8 to slide a drive device to be described later.

As shown in FIG. 6, the inclined chute 8 has an inclined surface 8a such that the end on the side of the blade 10 in the transverse direction is lowered.
Further, the upper end surface of the blade 10 has an inclined surface 10a such that the end on the side of the inclined chute 8 is lower in the transverse direction, and has a horizontal ridge line in the longitudinal direction. Next, the effect will be explained.

When the blade 10 is raised from the lowermost position of the parts storage section 7, the upper end surface of the blade 10 is an inclined surface 10a, so the parts 1 in the parts storage section 7 are moved up from the blade 10 as shown in FIG. 7A. They are lifted up while being placed in a line on the inclined surface 10a. And blade 10. When the upper end intersects the inclined chute 8, the parts 1 on the blade 10 sequentially fall onto the inclined chute 8 from the intersection side as shown in FIG. . If the component 1 becomes jammed at the outlet of the inclined chute 8 for some reason as shown in FIG. 7C, when the blade 10 descends downward as shown in FIG. Part 1 on chute 8
naturally falls into the parts storage section 7 and is thereby self-corrected. This is the same when the part 1 is full, so even when the part 1 is loaded up to the external chute 9, there is no need to stop the blade 10, and there is no need for a detector to detect that the part 1 is full. Unnecessary and many types of parts 1
When supplying a large number of units in multiple directions, this becomes a major factor in reducing the cost of the equipment. Incidentally, when the conventional device and the present device were measured in the manner shown in FIGS. 8A, B, C, and D, the results were as follows.

A is a conventional device in which the inclined chute 2 is made into a V-groove 3, B-D is the device of the present invention, B is a device with an inclined surface 8a of 1 plow, and C is a 15-pitch device.
The degree D is 2-sword. When the average supply amount per minute is measured for each under the same conditions, it is found that once a component is caught in A, it becomes impossible to supply it again, and a component removal device is required. 110 to 12 on the 10 degree slope of B
The number of pieces per minute is 12 to 137 pieces/min on the 15 degree inclined surface of C, and 140 to 146 pieces/minute on the 20 degree inclined surface of D. If the angle of the inclined surface 8a is increased, the inclined chute 8
Even if the part 1 is caught at the outlet of the blade 10, there is a greater possibility that it will fall by itself each time the blade 10 descends, resulting in an increase in the amount of supply per minute. In addition, in this case, part 1
The size is cylindrical, diameter 2Tfr111 length 677!7
F! The width of the blade 10 is 2 mm, and the length in the longitudinal direction is 120 Tf0fL.

Further, the cycle time of the blade 10 is 4 seconds per cycle. FIG. 9 shows the overall configuration of this device. Here, a base plate 5, an outer frame 6, a parts storage section 7, an inclined chute 8,
A large number of hoppers made of blades 10 etc. are arranged. In the figure, reference numeral 11 denotes a bracket for attaching a large number of blades 10 to each drive plate 12, 13;
4 is a bearing for supporting the weight of the drive plates 12, 13 and the blade 10 and vertically moving them; 15 is a guide shaft for this bearing 14, which is fixed to a support plate 16; The support plate 16 is provided with a longitudinally long elongated hole that allows the bearing 14 to move up and down. 17 is a motor for vertically swinging the driving plates 12, 13 and the blade 10; 18 is a crank; 19 is a swing shaft whose one end is attached to the crank 18; A connecting block connected to the drive plate 12, connected to the other end of the swing shaft 19 to move the drive plate 12, and connected to one end of the swing lever 23 via the lever 22, The other drive plate 13 is moved up and down.

The swing lever 23 supports the weight of a plurality of blades 10 attached to the drive plates 12 and 13, respectively, and the same number of blades 10 on the left and right sides are connected to both ends to maintain the weight balance between the left and right sides. ing. The swing lever 23 has a central portion rotatably supported by a shaft support 24,
Further, a connecting block 26 is connected to the other end via a lever 25 similar to the lever 22. This connecting block 26
The drive plate 13 is attached to the drive plate 13 via a connecting plate 27.
Next, its operation will be explained.

Now, when the motor 17 rotates in the direction of arrow a from the state shown, one end of the swinging lever 23 rotates in the direction of arrow b and the other end in the direction of arrow c, the drive plate 12 moves downward, and the other drive plate rotates. 13 moves upward. Furthermore, when the motor 17 rotates, the drive plate 12 goes up and the drive board 13 goes down. Along with this, the blade 10 moves up and down. Note that, due to the structure of this hopper, the stroke of the blade 10 is long, so in order to obtain a stroke that is twice the stroke of the crank 18, a mechanism (not shown) that doubles the stroke using a rack and pinion is used. is adopted.

As explained above, according to the present invention, by arranging a large number of compact hoppers into two sets and supporting the two sets in a balanced manner, the power of the drive source can be reduced, and the power of the drive source can be reduced. The number of motors used as a power source is also small, and the structure can be constructed at low cost.
