Detailed Description of the Invention

[0001]

[Industrial application] It is indispensable to supply the appropriate amount of the stored goods in the work such as assembling, processing, etc. for the manufacture of products, and in the work such as packaging of products, but there are a wide variety of products. It was extremely difficult to automate because of this. INDUSTRIAL APPLICABILITY The present invention enables temporary storage and replenishment of appropriate amounts of piled semi-finished products, parts, materials, etc. for processing, assembly, packaging, etc., and therefore can be used in all industrial fields. It is a thing.

2. Description of the Related Art Conventionally, a vibration type hopper, a lift type elevator hopper, a belt type hopper, etc. have been used for replenishing and storing articles. Since the vibration type requires the outlet to be narrower than the storage part, it is easy to cause clogging of articles near the outlet, and although the cost is low, the supply is often stopped. Elevator hoppers were also used for supplying and storing relatively large items, and were convenient because they were able to store a large amount of goods, but the supply amount was restricted by the size of buckets for frying and the interval between mounting of the buckets. However, it was difficult to supply an appropriate amount. The belt type hopper can adjust the fixed amount of supply by tilting the belt, but when the weight of the article becomes heavy, the friction between the belt and the pedestal increases, and the belt becomes stuck or damages the weight of the belt. It was impossible to supply heavy and large articles. In addition, there are those that attach a crosspiece to the belt to supply articles that are easy to roll and those that quantify, but if a large number of articles get on the belt, the crosspiece pushes a large number of articles. In addition to the large force applied to the crosspiece, the damage to the crosspiece is severe, and the articles are transferred in piles across the crosspiece, which makes it difficult to quantify. When a partition plate is provided above the belt for quantification, articles are often sandwiched between the partition plate and the crosspiece to make it impossible to supply the articles. The method described in the patent application (Japanese Patent Application No. 4-178804) filed by the applicant on May 27, 1992 “Article transfer method and device” is intended only for horizontal movement of articles. Therefore, there is no consideration about the storage of articles, there is no storage part where the articles are temporarily stored,
It has no means for pushing up the stored articles diagonally and replenishing them in a substantially constant amount.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the belt type hopper, and a method and apparatus for replenishing the article moving method described in Japanese Patent Application No. 4-178804 filed by the applicant earlier. Is applied to. In a belt type hopper, the belt moves while receiving the total weight of the articles stored in the hopper to transfer the articles, so that the belt is strongly pressed against the pedestal and the friction with the pedestal is large. Therefore, not only a very large force is required to drive the belt, but also the belt is damaged. The present invention lifts and moves a part of the stored articles to extremely reduce the relative movement between the belt and the pedestal, reduce the driving force required to move the stored articles, and increase the movement of the belt. The purpose is to obtain a hopper that can prevent body damage. Therefore, the present invention is such that the weight of the article is only partially applied to the belt-like body, and the quantity of the article on the belt is averaged, so that it is possible to supply an appropriate amount.

FIG. 1 is an explanatory view showing a cross section of the present invention viewed from the side, and FIG. 2 is an explanatory view viewed from above. Two base materials 1-1 that are inclined and installed in parallel
And 1-2 (1 in FIG. 1, 1 in FIG. 2)
-1 and 1-2, and likewise in FIG.
The numbers 1 and -2 are attached. The base material 1 is installed by a member (not shown) so as to maintain an appropriate inclination with respect to the ground. The case 6 is attached above the base materials 1-1 and 1-2 through a member (not shown). Both side surfaces of the case 6 are on the upper extension of the base material 1, and the rear part is composed of three planes of the back surface installed above the lowest portion of the base material 1, and is released toward the higher side of the base material 1. ing. A rotary shaft 21 is rotatably supported on the front part of the substrate 1 and a shaft 22 is rotatably supported on the rear part thereof. The rotary shaft 21 or the shaft 22 is driven by a motor (not shown). A pulley 23-1 is fixed to the rotary shaft 21 inside the base material 1-1, and a pulley 24-1 is attached to the shaft 22.
Is fixed. In addition, the rotating shaft 2 is provided inside the base material 1-2.
A pulley 23-2 is fixed to the shaft 1 and a pulley 24-2 is fixed to the shaft 22. The belt 2-1 is wound around the pulleys 23-1 and 24-1, and the pulleys 23-2 and 24
The belt 2-2 is wound around -2. The belt 2-
A receiving plate 7 is installed on the base material 1 between the upper surfaces of 1 and 2-2 by a member (not shown). The protrusions at both ends of the roller 4 are rotatably supported in the holes 41 provided in the support plate 43, and the support plate 43 is arranged so that the rollers 4 are parallel to the shafts 21 and 22 that are supported at both ends of the base material 1. Is fixed to the belts 2-1 and 2-2. The roller 4 is installed immediately above and not in contact with the pedestal 7.
The support plate 44 is attached at a point where the length of the belt 2 is equally divided with respect to the position where the support plate 43 is attached to the belts 2-1 and 2-2. It does not change the gist of the present invention to set the number of supporting plates to two sets or an appropriate number of two or more sets depending on the supply capacity of the supply device of the present invention. Using a chain for the belt 2 and using a chain wheel for the pulley does not change the gist of the present invention. A case where two sets of support plates are used to avoid complication will be described. A shaft 42 at both ends of the same roller 40 as the roller 4 is rotatably supported by the support plate 44. On the upper surface of the pedestal 7, there is provided a band-shaped body 3 that is flexible in the length direction and flexible in the width direction. The rear end of the strip 3 is fixed to the back surface of the case 6. The strip 3 is laid along the upper surface of the pedestal 7, envelops the upper surface of the roller 4, and is further laid along the upper surface of the pedestal 7, and the tip of the strip 3 is attached to the shaft 21 at the front end of the substrate 1. It is a free end that hangs over. Therefore, since the front-back movement of the belt-shaped body 3 is not restricted, the tip end portion 31 of the belt-shaped body 3 envelopes the roller 4 by the movement of the roller 4 and is not separated from the pedestal 7. A portion of the band-shaped body 3 that encloses the roller 4 is called a bulge.

[0005]

The operation of the present invention will be described with reference to FIG. FIGS. 3 and 4 supplement the description of this operation. The rotary shaft 21 is connected to a drive element such as a motor (not shown),
The belt 2 is rotated so as to rotate counterclockwise and pull up the upper surface of the belt 2 from the lower side to the higher side. By the rotation of the belt 2, the support plate 43 attached to the belts 2-1 and 2-2 moves diagonally upward and the support plate 44 diagonally downward, so that the roller 4 is pulled up diagonally and at the same time the roller 40 is pulled up.
Move diagonally down. Since the roller 4 is enveloped by the strip 3, the roller 4 rotates clockwise due to friction with the back surface of the strip 3. Since the rear end of the strip 3 is fixed to the back surface 8 of the case 6 by the movement of the roller 4, the front portion 31 of the strip 3 is pulled up by the roller 4. Thus, the bulge of the band-shaped body 3 that envelopes the roller 4 moves obliquely upward from the case back surface 8 and reaches the tip of the base material 1. Third
The drawing shows the case where the roller 4 (the roller at this time is shown as 45) is near the back plate of the case 6. The roller 45 passes under the back plate of the case 6 and arrives at the position shown in the figure. Third
In the state shown in the figure, the strip 3 is placed on the pedestal 7, and the tip 31 of the strip is pulled up and hung down. When the roller 4 continues to move, the state shown in FIG. 1 is obtained. The front and rear portions of the belt-shaped body 3 of the roller 4 are placed on the pedestal 7. When it is further moved, the roller 4 reaches the front end and enters the state shown in FIG. 4, and the strip 3 at the rear portion of the roller 4 is placed on the pedestal 7 over its entire surface, and the roller 4 (indicated by 46 in the figure). The belt-like body 3 on the front surface of the is stretched between the belt 21 and the shaft 21. When the roller 4 is further moved, the support plate 43 is fixed to the belt 2 so that the belt 2 is wound around the pulley 21.
Go around 1. Therefore, the roller 4 moves to the lower side of the substrate along a semicircular orbit centered on the shaft 21. Band-shaped tip 3
1 is in a state of being pulled down by the roller 4 when the roller 4 wraps around. Therefore, the strip 3 is pulled forward just before the roller 4 goes around,
When the wraparound is completed, the belt 3 is pulled back to the beginning due to its own weight and the weight of the article. The roller 40, which is attached to the belt 2 symmetrically with the roller 4, first moves to the lower left of the lower side of the belt 2 and moves to the lower right, and when the roller 4 rotates around the front end, goes around the rear end and comes out above the substrate 1. . Thus, the state shown in FIG. 3 is restored. This operation is repeated to replenish the articles. Next, the operation when the parts are put into the apparatus of the present invention and supplied will be described with reference to FIGS. 5, 6 and 7. In the state shown in FIG. 5 in which the roller 4 is at the 45 position, it is assumed that the article is loaded into the case 6. When the roller 4 starts moving forward, the band 3 is lifted by the roller 4. Belt 2 is driven and roller 4
When is pulled forward, it looks like Fig. 6. That is, the belt 4 pulls the roller 4 forward, but since the belt-shaped body 3 enveloping the roller 4 is pressed against the roller 4 by the article, the belt-shaped body 3 is lifted up, and the roller 4 is rotated. Rotating in the direction, the strip 3 lifts up the article above it. Some of the articles are pushed and moved forward while rolling or sliding on the strip 3, but when a large amount of articles are stored, they are lifted upward without moving forward. Further, when the roller 4 advances and the amount of the stored articles decreases in front of the roller 4, the belt 4 lifts the belt-shaped body 3, so that the article rolls forward. That is, when there are many articles in front of the roller 4, the article is lifted up as the strip 3 is lifted up, and the article lifted by the forward movement of the roller 4 falls to the back surface of the roller 4. When the amount of the article in front of the roller 4 is small, the article in front of the roller 4 is pushed by the roller 4 while the roller 4 moves forward and is moved forward by the roller 4. That is, if the amount of the article in front of the roller 4 is large, the friction between the strip 3 and the article increases, and the article is lifted up by the roller 4 while remaining on the strip 3 and the local accumulation collapses. If the amount of the articles in front of the roller is less than a certain amount, the average deposition is called (this is called leveling), and the articles are pushed by the bulge of the belt-like body 3 by the rollers 4 and pushed forward to be replenished. . The strip 3 on the back surface of the roller 4 is pushed back onto the pedestal 7 by the weight of the strip 3 and the weight of the article. Further, when the roller 4 moves forward, the state shown in FIG. 7 is reached, and the moving roller 5 is pushed forward by the roller 4, the belt-shaped body 3 becomes a downward slope from the upper part of the roller 4 to the shaft 21, and the article falls forward to the next position. It will be supplied to the process machine. The belt-shaped body front portion 31 is pushed by the roller 4 and moves to the frontmost position. The roller 4 wraps around the lower side of the pedestal 7 along the pulley 23. In this state, the roller 4 is in the state of 45, and the other roller 40 attached to the belt 2 goes around the pulley 24 and reaches the back surface of the case 6, so the state is the first state in this description.
Further, in the state shown in FIGS. 6 and 7, the belt-shaped body 3 behind the roller 4 is pressed against the pedestal 7 by the weight of the parts.
In the case of FIG. 7, the roller 4 is in the most pulled state. When the roller 4 moves around the pulley 23 and moves downward, the strip 3 is pulled back toward the back surface of the case 6 by the weight of the strip and the weight of the components. Thus, when the component falls forward, the next roller starts to push it forward while being lifted by the roller from the back surface of the case 6. This operation is repeated to supply the parts.

[0006]

[Example] When the front end of the belt-shaped body is in a free state, the weight of the hanging portion does not cause the belt-shaped body 3 to return to the initial position,
Next, when the roller 4 pushes the article, the front surface of the roller 4 may be gently inclined, and the article may not be pushed and the roller 4 may get over the roller 4 to be unable to be replenished. Therefore, in order to return the band-shaped body 3 to the initial position, the base material 1 is extended forward as shown in FIG. 8, and the elongated hole 52 is provided in the extended portion. The moving roller 5 has a sliding shaft 51 at both ends, and the sliding shaft 51 is a base material 1.
Slide the long hole 52 provided at the tip of the. Therefore, when the tip of the band-shaped body 3 is fixed to the moving roller 5, the band-shaped body 3 expands and contracts on the upper surface of the pedestal 7 as the moving roller 5 slides. It does not change the gist of the present invention to always pull the sliding shaft 51 to the rear end of the elongated hole 52 by a spring or the like (not shown). Roller 4 is base material 1
When the belt 2 bends downward at the front end of the roller 4, the roller 4 also bends downward.
The moving roller 5 and pushes the moving roller 5 forward.
The shaft 51 slides in the long hole 52, and the moving roller 5 moves forward. When the roller 4 further moves and wraps around the lower side of the substrate 1, the weight of the belt-shaped body 3 and the weight of the article, and if there is a spring attached to the sliding shaft 51, the sliding shaft is pulled back to its original position by its force. The band-shaped pair 3 contracts and is drawn toward the back surface of the case 6. In this embodiment, when the roller 4 reaches the front end of the substrate 1, the belt-shaped body 3 becomes a downward slope from the upper part of the roller 4 to the moving roller 5, and the article falls forward and is supplied to the machine of the next step. Become. The moving roller 5 is pushed by the roller 4, the sliding shaft 51 of the moving roller moves in the long hole 52, the moving roller reaches the tip of the long hole 52, and the roller 4 wraps around the underside of the pedestal 7. . See also roller 4
The belt-shaped body 3 on the rear side of is pressed against the pedestal 7 due to the weight of the parts, but when the roller 4 turns downward, it is pulled to the frontmost position. When the roller 4 moves around the pulley 23 and moves downward, the strip 3 is pulled back toward the back surface of the case 6 by the weight of the strip and the weight of the components. Thus, when the component falls forward, the next roller begins to push it forward while being lifted by the roller from the back surface of the case 6.

FIG. 9 shows an embodiment in which four rollers are attached to the belt 2 at equal intervals in order to increase the supply amount of the article, and a metal mesh having flexibility and stretchability in the length direction is used as the band-shaped body 3. Here is an example. In FIG. 9, rollers 4-1 and 4-
2, 4-3 and 4-4 are attached to the belt 2 at equal intervals. The rear portion of the flexible strip 3 is fixed to the back surface of the case 6, has a slack between the roller 4-2 and is in contact with the pedestal 7. The strip 3 covers the upper part of the roller 4-2, and between the roller 4-1 and the roller 4-2, 3-
2, which is in contact with the cradle 7. Further, the strip 3 surrounds the upper part of the roller 4-1 and reaches the moving roller 5. Rollers 4-3 and 4 corresponding to rollers 4-1 and 4-2
-4 is attached to the belt 2 on the lower side. When this is done, the state of the articles becomes as shown in FIG. 10, and many articles are stored between the upper portion of the roller 4-2 and the back surface of the case 7, and between the rollers 4-1 and 4-2. The articles are flattened to a flat, low storage state. Since there is little accumulation of articles in front of the roller 4-1, the article is pushed while being rolled by the roller 4-1 and supplied to the machine of the next process. Further, since the belt-shaped body 3 is lifted by the roller 4-1, an article is also lifted, and an article exceeding the amount of the article determined by the height of the roller 4-1 is lifted on the roller 4-1 and is lifted by the roller 4-1. As it moves forward, it falls to the back of the roller 4-1. Since there are four rollers, the supply amount can be increased. Increasing the number of rollers depending on the length of the band does not change the gist of the present invention. In this embodiment, by using a wire mesh, the friction between the belt-shaped body and the article can be reduced, and the force of pushing the article by the roller 4 can be reduced.

[0008]

Industrial Applicability According to the present invention, since articles can be temporarily stored and leveled and supplied, it is considered that it greatly contributes to labor saving and rationalization of supply and supply of articles in various industries. . In particular, it is considered to be extremely large in contributing to the supply of relatively heavy articles.
