Description

[Detailed description of the invention] [Field of industrial application] The present invention is a parts feeding device that supplies similar parts such as hooks, rivets, buttons, screws, or rivets in a predetermined amount at a time, and is capable of supplying these parts completely without clogging. Regarding the hopper that was made to be ejected.

[Conventional technology and its problems]

Conventionally commonly used parts feeding devices are designed to prevent parts from remaining in the hopper.
The hopper is vibrated to eject the parts, or air is supplied to blow the parts away. However, in the hopper of such a component supply device, the hopper must be constantly vibrated, so that the components repeatedly collide with each other, resulting in damage to the components. Also, since vibrations and air are supplied to the hopper more than necessary,
Since the parts stored in the hopper are agitated more than necessary, most of the parts are damaged to some extent and extra power is required.

[Means for solving problems]

The present invention was devised with the aim of solving these problems and ejecting parts from the hopper with a simple structure without leaving any parts behind.

Since the hopper has a pair of guide members 65 fixed thereon, each having slopes 65a and 65b, the distance between which increases toward the top and rear of the hopper, parts can be completely supplied.

[Effect]

A predetermined amount of parts are charged and stored in the hopper 60, and as a result, the parts are successively scooped upward by the scooping member 77 of the belt 76 as a predetermined operation is repeated. This causes the parts to flow toward the supply port 64 of the hopper 60. At this time, the parts are guided by the guide member 65 and gathered at the supply port 64.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained using a hook staking machine with reference to the drawings. In Fig. 5, 60a and 60b are upper hook 2 and lower hook 3.
It is a hopper that stores a predetermined amount of each. These hoppers 60a, 60b are fixed on a support 71 via a guide plate 70. Since these component feeding devices having the hoppers 60a and 60b for the upper hook and lower hook have the same configuration, the feeding of the upper hook 2 will be explained here.

Guide plates 70 parallel to each other are fixed upright on the support column 71, and a belt 76 that is driven in circulation by a motor 75 fixed to the guide plates 70 is disposed between the guide plates 70. As shown in FIG. 2, this belt 76 is fitted with a large diameter part of the stepped upper hook 2 on the scooping side, that is, the side on which the belt 76 rises, and has an inclined shape so that it rolls in a fixed direction. Scooping member 7
7 are installed. A supply path 40 such as a chute or rail is attached to the upper part of the moving scooping side of the belt 76 so as to be inclined forward and downward so as to guide the upper hook 2 scooped up by the scooping member 77 forward. There is.

Furthermore, as shown in FIG. 2, a side plate 61 constituting a hopper 60a is fixed at a position close to the belt 76 at the bottom of the guide plate 70, and the bottom 60c of this hopper 60a has a tip thereof. The shutter plate 62 is fitted so as to be freely movable back and forth until it reaches a position where the belt 76 contacts the locus of movement of the scooping member 77. This moving distance is determined by a guide groove 62a formed in the shutter plate 62 and a movement regulating member 62b such as a screw, bolt, or pin fixed through the guide groove 62a. The bottom 60c of this hopper 60a
slopes downward from the rear to the front. Further, as shown in FIGS. 1, 3, and 4, a blocking wall 63 is attached to the side of the hopper 60a that is in contact with the belt 76.
3 is provided with a gate 63a whose height is adjustable to adjust the opening amount of the lower supply port 64. The part surrounded by the blocking wall 63, the bottom part 60c, and the side plate 61 has a shape that allows the upper hooks 2 to flow without stopping and gather at the supply port 64, which has a width comparable to the width of the belt 76, for example. , bottom 60c

7 is made of transparent resin, and the amount stored in the upper hook 2 can be checked at a glance from the outside. Further, as shown in FIG. 5, on both sides of the belt 76 to which the scooping member 77 is fixed between the entrance of the supply path 40 on the scooping side and the supply port 64 of the hopper 60a, there are belts 76 held by the scooping member 77. A side wall 68 is arranged to prevent the hook 2 from falling.

Furthermore, a frame 1 is installed in front of this parts supply device.
stands upright, and a stem 6 and an anvil 7 are arranged at the front of the frame 1 to face each other. This stem 6 is adapted to be operated by the back and forth movement of the working rod 11. This action rod 1
1, one end of an elevation transmission member 13, which is swingably supported by the frame 1, is fixed to the rear end of the elevation transmission member 13 so as to be adjustable in position, and the other end is connected to a drive source (not shown). A lifting operation rod 14 is connected. Further, this lifting/lowering operating rod 14 is arranged at the tip of the supply path 40 and operates a separating means 50 that separates the upper hooks 2 one by one for each work cycle. Furthermore, in addition to this, the pushing member 30 that is separated and forcibly supplies the upper hook 2 to the tip of the stem 6 is operated, and the lower hook 3 is moved onto the anvil 7 on the same center line as the stem 6 every work cycle. The lower hook supply unit is operated to supply one piece at a time. Further, these are each operated via a timing linkage mechanism (not shown), and the lower hook 3 is connected to the hopper 6.
It is configured such that it is supplied onto the anvil 7 from the upper hook 2 through the supply path 41 at the same time as the upper hook 2 is supplied.

Next, the operation of this embodiment will be explained. With a predetermined amount of upper hooks 2 stored in the hopper 60a, when a signal to start work is input, the belt 76 moves upward on the scooping side. This allows the second
As shown in the figure, the upper hooks 2 supplied from within the hopper 60a enter the scooping member 77 with the large diameter portion of the upper hooks 2, and are scooped out while being aligned in a predetermined direction. In this way, since the upper hooks 2 are scooped up from the earliest ones, they are guided by the bottom slope inside the hopper 60a and the slopes 65a and 65b of the guide members 65 on both sides of the supply port 64, and are gathered at the supply port 64. Therefore, the upper hook 2 is gradually supplied from the supply port 64 without stopping midway. At this time, if the amount of upper hook 2 supplied from this supply port 64 is small,
By moving the gate 63a upward,
Further, when a large amount of upper hooks 2 are supplied from the supply port 64, the amount of upper hooks 2 supplied from the supply port 64 can be adjusted by moving the gate 63a downward.

On the other hand, the upper hook 2 supplied upward in this manner is scooped up by the scooping member 77 until it reaches the outlet 78 shown in FIG. 5, and is prevented from falling by the side wall 68, so that this state When the upper hook 2 reaches the outlet 78, the scooping member 7
7 into the supply channel 40. As a result, they move within this supply path 40 and are aligned and stored therein. Moreover, the supply operation of the hook 2 is carried out through this supply path 40.
When a predetermined amount is aligned and stored, the movement of the belt 76 is stopped so that no more is supplied, and when caulking is performed during this stop and the amount becomes less than the predetermined minimum amount, the belt 76 moves again and the upper hook 2 is stored. The supply of

Then, in a state in which the upper hooks 2 are supplied one by one along with the lower hooks 3 supplied in advance for each work cycle and are held at the respective positions of the stem 6 and anvil 7, a switch (not shown) for starting the work is activated. When the stem 6 is inserted, the stem 6 descends and swages the upper hook 2 and lower hook 3 onto a workpiece (not shown). When the work is completed in this manner, the stem 6 subsequently starts to rise, so that the workpiece can be taken out to the outside. On the other hand, this stem 6
The pushing member 30, which is interlocked with the start of the upward movement, pushes the next upper hook 2 into the catcher 5.

[Effect of idea]

As is clear from the embodiments described above, the present invention provides a component supply system in which a predetermined amount of components stored in the hopper 60 is arranged and supplied upward by a scooping member 77 fixed to a belt 76 that circulates up and down in front of the hopper 60. In the apparatus, the bottom 60c of the hopper 60 is formed to be inclined forward and downward, and a gate 63a, which is height-adjustable, is attached to the front surface of the hopper 60 approaching the lower end of the bottom of the hopper 60 to open and close the supply. A supply port 64 is formed, and the supply port 64 is
This is a hopper to which a pair of guide members 65 are fixed, each having slopes 65a and 65b on both sides of the hopper 60, each having slopes 65a and 65b whose distance from each other widens toward the top and rear of the hopper.

Therefore, parts such as hooks, rivets, or rivets can surely slide toward the supply port without stopping in the hopper, and the parts can be completely supplied. Furthermore, since the parts are not agitated in the hopper, there are no scratches, no defective products, and improved product reliability. Furthermore, in order to smoothly feed parts, a drive source to vibrate the hopper and an air source to blow out parts were previously required, but these are all no longer needed, resulting in energy savings. You can obtain unique effects such as
