Description

[Detailed Description of the Invention] The present invention relates to an automatic feeding device. For example, in a clothes cleaning factory, when objects suspended on a conveyor rail are sent at a constant stroke, the stroke interval is changed as necessary at a certain point. This invention relates to an automatic feeding device capable of feeding in short, small increments.

In a clothing cleaning factory, a large amount of items are hung on hangers, and the hangers are suspended from a conveyor rail that extends horizontally in the air. A feeding mechanism is adopted in which the hanger is intermittently fed in one direction by the reciprocating movement of a large feeding claw. This large feed pawl is connected to a drive motor and repeats horizontal reciprocating motion with a constant stroke.In the forward direction, it holds the hanger and moves it, and in the backward direction, the pawl rotates and moves the hanger. Because it is structured so that it passes over the top, the hanger is always fed intermittently only in one direction. On the other hand, the clothes on the hangers that are sent to us are processed in a certain way in each process, which is a so-called assembly line process, but depending on the process, it takes a long time to process the clothes. Processing may not be able to keep up with the flow. To eliminate this inconvenience, the width of each stroke of the hanger being fed may be shortened at a certain arbitrary location to slow down the flow of clothes at that location. Against this background, we investigated a feeding device with a shorter stroke width than conventional conveyors, and as a result, we arrived at the present invention.

Therefore, the purpose of the present invention is to move articles intermittently by the movement of rods within the conveyor rail without requiring external force such as large claws that suspend hanging hangers on conveyor rails as in the prior art. The object of the present invention is to provide an automatic feeding device capable of feeding a loose item with a width smaller than the stroke width when using the stroke of a large claw.

That is, in the present invention, the conveyance rail is formed into a hollow shape, and a linear slit of an appropriate length is opened upward along the longitudinal direction in the conveyance rail, and the conveyor rail is provided with a linear slit of an appropriate length. Insert a feed rod with a feed rod that is capable of raising and lowering only in response to a horizontal force from one direction, and set the feed rod so that its upper end protrudes from the slit so that it is wider than the spacing between the large feed claws. A plurality of pins are arranged at regular intervals with small intervals, and pins perpendicular to the feed rod are placed at appropriate locations on the feed rod so that the tips of the pins are in the midsection of the conveyor rail and are longer than the stroke of the large feed claw. The pin has a small length and is protruded from an open long hole, and the pin is provided so that it can be pressed in one direction by a large feed claw, and at one end of the feed rod there is always a pin that is opposite to the direction in which the pin is pressed. The gist of the present invention is an automatic feeding device characterized by interposing a spring that biases the device in a direction.

The present invention will be explained in detail below with reference to the drawings. FIG. 1 is a side view showing a conveyor system in a cleaning factory incorporating the feeding device of the present invention. In the figure, 1 is a drive unit, 2 is a conveyor rail, 3 is a large feed claw, 4 is a conveyance rail, and 5
is a hanger, and 6 is a garment. Figure 2 shows the drive section 1.
FIG. 2 is an enlarged cross-sectional view of FIG. 2, and the structure near the drive section will be explained with reference to FIG. A drive motor 7 and a speed reducer 8 are installed on the drive section 1, and a rotating shaft 9 protrudes from the speed reducer 8 inside the drive section 1 and rotates the arm 10. A crankshaft 11 is rotatably provided at the tip of the arm 10, and a slider 13 that can slide horizontally on the circumferential surface of a slide rod 12 is reciprocably provided at the other end of the crankshaft 11. The lower end of the slider 13 is fixed to a conveyor rod 14. The conveyor rod 14 is inserted into a tubular conveyor rail 2 having a slit at the bottom, and can be moved horizontally within the conveyor rail 2 by rotating runners 28 on both sides. A large number of pendants 15 are arranged at regular intervals under the conveyor rod 14, and the pendants 15 are provided with large feeding claws 3 so as to be swingable. However, this large feed pawl 3 swings around the shaft 16 and loses drag against the force in the direction of arrow A, but when faced with the force in the direction of arrow B, it rotates further from the vertical position as shown in the figure. It has a unique structure. Further, the large feed pawl 3 rotated by the force in the direction of arrow A is structured so that it returns to the vertical position in the figure by its own weight as soon as the pushing force is removed. A transport rail 4 extending parallel to the conveyor rail 2 is fixed to the conveyor rail 2 by a support 17 (see FIGS. 1 and 3) below the conveyor rail 2. Transport rail 4
As will be explained later, it has a tubular shape, and the feed rod 1 is placed inside it.
8 (see Figures 3 and 4), a long hole 19 is provided in the middle of the conveyor rail 4, and a pin 20 fixed perpendicularly to the feed rod 18 is inserted through the long hole 19.
stands out. The tip of this pin 20 is in contact with the large feed claw 3 when it moves horizontally.

In FIG. 1, the place where the feeding device of the present invention is installed is the lower part of the figure where clothes are concentrated, and FIG. 3 is an enlarged view of this part.

In FIG. 3, a tubular feed rod 18, which also has a slit at the top, is inserted into the tubular conveyance rail 4, which has a longitudinal slit at the top, and connecting rods 21 are present at appropriate locations. , a spring 22 is wound around the connecting rod 21. A spring support piece 23 that slides on the inner wall of the conveyor rail 4 is provided at both ends of the spring 22. One end of the spring support piece 23 on one side is fixed to the connecting rod 21 with a ring 24, and the spring support piece 23 on the other side is fixed to the connecting rod 21 with a ring 24. The end portion is in contact with a stopper 25 protruding from the inner wall of the transport rail 4. The feed rod 18 has feed pawls 26 arranged at equal intervals smaller than the spacing between the large feed pawls 3 and a shaft 27.
It is swingable around the center. However, this feed claw 26 rotates around the shaft 27 and does not exert any resistance against a force in the direction of arrow C, but it rotates further from the vertical position in the figure in response to a force in the direction of arrow D. It has a unique structure. Further, the feed pawl 26 rotated by the force of arrow C is structured so that it returns to the vertical position shown in the figure under its own weight as soon as the force C disappears.

FIG. 4 is an enlarged cross-sectional view of the main parts of the conveyor system of this embodiment, showing the support 17 that fixes the conveyor rail 2 and the conveyor rail 4, the tubular conveyor rail 2 having a slit at the bottom, and the support 17 that is inserted into the support 17, which has a slit at the bottom. slide rod 14, conveyor rail 2
A runner 28 rotating on the inner wall of the pendant 15, a pendant 15 hanging from the slide rod 14,
A large feed claw 3 swings around a shaft 16 at the tip of 5.
I can see it. Further, inside the annular conveyance rail 4 having a slit at the top, there can be seen a tubular feed rod 18 which also has a slit at the top, and a feed pawl 26 provided on the feed rod 18 and swinging about a shaft 27. Furthermore, it is fixed to the feed rod 18 perpendicularly thereto, and is fixed to the elongated hole 19 (the first,
The protruding pin 20 is visible (see Figure 2).

Next, the operating conditions and effects of this embodiment will be explained with reference to FIGS. 1 to 4.

By driving the drive motor 7, the arm 10
rotates, and the slider 13 reciprocates along the slide rod 12 by the crank mechanism. Since the slider 13 is fixed to the slide rod 14, the large feed claws 3 reciprocate in the horizontal direction accordingly. The stroke width of this reciprocating motion is L, which is set slightly larger than the arrangement pitch P of the large feeding claws 3. Now, to explain the movement of clothes with reference to the lower right diagram of FIG. 1, large feeding claws 3a, 3b, and 3c arranged in a pitch P are applied. If the large feed claw 3 is moved with a stroke L slightly larger than the arrangement pitch P of the large feed claw 3, taking into account the amount of time it will cross over the hanger 5 during reciprocation, the garment 6 will move to the left by the arrangement pitch P of the large feed claw 3. and stands still. More specifically, the reciprocating width of the large feed claw 3 is L.
However, when a force is applied from the right side of the large feed claw 3, the large feed claw 3 rotates around the shaft 16 and does not exert any resistance, so it climbs over the hanger 5 and returns to its original position. That is, the clothes 6a are moved to the position 6b, and the clothes 6b are moved to the position 6c.
This means that 6c has moved to 6d. In this way, the clothes are sent intermittently at intervals of pitch P. Next, the clothes sent from position 6c to position 6d are sent from position 6c to position 6n as shown in Figure 1.
Since the large feed claw 3 is not suspended over a certain range up to the position, the feed device of the present invention is provided with a small width from this point. The movement of this feeding mechanism will be explained with reference to FIGS. 1 to 3. In Fig. 2, when the large feed claw 3 moves to the left with a stroke of width L, the pin 2
0 and press it by a width l. Since the pin 20 is located below the drive section 1 and fixed near the tip of the feed rod 18, the feed rod 18 also moves by the width l. At this time, the spring 22 shown in FIG. 3 contracts as the feed rod 18 moves, and a force acts to return the feed rod 18 to its original position. Large feed claw 3
When the rod starts to take the return path, the feed rod 18 is moved by the spring 2.
2, it returns again by the width l. That is, as the large feed pawl 3 reciprocates with a stroke L, the feed rod 18 and the feed pawl 26 fixed thereto reciprocate with a stroke l. The feed claws 26 are arranged with a pitch p, and have a stroke l.
The width of is slightly larger than that of pitch p. 1st
Returning to the figure, during the next stroke, the garment 6a fed by the large feeding claw 3c is pushed by a width p by the stroke of the width l of the feeding claw 26a, and stops at a position 6e. As already explained, the feed claw 26 exerts a force to push the hanger 5 to the left, but cannot push it to the right, and returns to its original position by rotating and passing under the hanger. In other words, the clothes that have been fed by the width P in one stroke up until now will be fed by the width P after being fed to the narrow width feeding device of the present invention, and the feeding speed will be relatively small. The clothes 6n that have come out of this small-width feeding device are again fed by a width P by the large feeding claw 3n. Therefore, by installing this narrow feeding device in a place where the cleaning operation is complicated and it is desired to slow down the feeding of clothes, it is possible to freely change the feeding speed of the clothes using a single drive device.

Although the embodiment in a cleaning factory has been described above in FIGS. 1 to 4, the feeding device of the present invention is not limited thereto and can be applied in a wide range of applications.
