Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sorting object automatic supply machine for efficiently supplying a sorting object to a sorting machine, for example, an automatic feeding machine such as long fruit vegetables such as carrots.
[0002]
[Prior art]
Conventionally, in order to automatically supply harvested carrots and other fruits and vegetables to a weight sorter, for example, as shown in Japanese Examined Patent Publication No. 7-12336, it is higher than the support surface means 3 on the surface of the inclined surface for conveyance, and is also a support surface. By disposing the drop-off pieces 10a to 10c in a projecting manner in a place biased toward the moving side of the means 3 and immersing them against the elasticity, the extraneous carrots and the like of the rollers 1 adjacent to each other in the vertical direction are arranged. It can be more reliably dropped from the gap, and carrots and the like can be continuously and reliably supplied to a sorter and the like one by one.
[0003]
On the other hand, as shown in Japanese Patent Laid-Open No. 5-14022, the supply unit is composed of a conveyor in which rod-shaped bodies are attached to a pair of left and right endless belts at intervals, and this conveyor is arranged in an upward gradient toward the selection unit. In addition, since the convex portion 39 is provided on the peripheral surface of the rod-shaped body 12 and the rotation means 33 and 34 for rotating the rod-shaped body 12 are provided, the agricultural product P such as carrot is received by the sorting portion A for weighing. One can be supplied to the body 2 one by one.
[0004]
However, the above-described conventional technique has a drawback in that carrots may be damaged because protrusions are provided in the supply path. In addition, the form of agricultural products such as carrots is quite different, and the form of each one is different, and in the conventional technology, when two different sizes of ginseng overlap between rollers, there is a possibility that it can be separated into one However, when two or more carrots of the same size overlap at the same time, the above-mentioned conventional technology is a method in which carrots are supplied while the conveyor itself moves in the transport direction by an endless conveyor. There is a problem that it is technically very difficult to align it. Therefore, in the end, there was no method other than correcting this manually, and the degree of supply automation was insufficient. Furthermore, since it is an endless conveyor, the machine itself tends to be large.

[0012]
DETAILED DESCRIPTION OF THE INVENTION
A configuration of the carrot automatic feeder 1 shown in FIGS. 1 to 11 will be described. As shown in FIG. 1, the automatic carrot feeder 1 pulls out the carrot 3 (see FIG. 12) from the hopper 16 via the belt conveyor 17, and reliably supplies the carrot 3 to the carrot weight sorter 2 one by one. (See arrow). The carrot automatic supply machine 1 includes a machine body 4, two parallel and predetermined support members 5 arranged on the machine body 4 in an upward gradient toward the carrot weight sorter 2, and the support members 5. A return path 6 for returning the carrot 3 provided on the left side to the hopper 16 and an ascending gradient in a direction orthogonal to the support member 5 at a predetermined interval (lateral direction) in a row so as to be rotatable with respect to the support member 5. 16 rotating shafts 7a to 7p arranged in an aligned manner, and a rotating shaft 8 (see FIG. 11) provided in the carrot weight sorter 2 that rotates these rotating shafts 7a to 7p in a predetermined direction in synchronization. The first disk group 9 and the up-gradient path composed of the second disk group 10 are provided so as to be eccentric to the rotating shafts 7a to 7p and aligned and fixed. These two disk groups 9 and 10 form a characteristic configuration of the present embodiment. As shown in FIGS. 2 to 8, a first disk group 9 composed of eight disk subgroups 9a to 9h arranged on the rotating shafts 7a, 7c,... 7o, respectively, and the rotating shafts 7b and 7d. ,..., 7p, each of which is composed of eight disk subgroups 10a to 10h that are arranged in groups of five. That is, the first disk group 9 and the second disk group 10 are alternately arranged on the odd-numbered and even-numbered axes with respect to the rotation axes 7a to 7p, respectively. In the feeder of the prior art, the conveyor member itself such as a conveyor belt and a chain circulates endlessly to convey the carrot 3, but in this embodiment, the structure (technical principle) is fundamentally different from this. The carrot 3 is transported by rotating (spinning) at the position of the disk. That is, unlike the conventional case, the disk does not move in the moving direction of the carrot 3. Returning to FIG. 1, sprockets 11a to 11p are fixed to the right ends of the rotary shafts 7a to 7p, respectively, and an endless chain 12 is wound around them, and the rotary shafts 7a to 7p rotate in synchronism at the same speed. It can be done. That is, the rotation shaft 7p in the rightmost part (in FIG. 1) is connected to the rotation shaft 8 via the endless 13 and the sprockets 14 and 15 (see FIG. 11), and the power is transferred from the rotation shaft 8 to the rotation shaft 7p by the endless chain 13. Is transmitted, and the rotating shaft 7p is rotated by the endless chain 12 (see FIG. 1), so that the rotating shafts 7a to 7p can rotate in synchronization. That is, the carrot automatic supply machine 1 is supplied with a drive source from the carrot weight sorter 2. In addition, the gear ratio and the like are set so that the carrots 3 are delivered one by one from the carrot automatic feeder 1 to the carrot weight sorter 2 one by one. In some cases, an appropriate configuration ratio can be arbitrarily selected as the gear ratio. For convenience, the power source is supplied from the carrot weight sorter 2, but it goes without saying that the power source can be separately installed on the carrot automatic supply machine 1 side.
[0013]
2 to 5, if FIG. 2 is an initial state (initial position), FIG. 3 shows a state after the disk has made a quarter turn, and FIG. 4 shows a state after a further quarter turn. FIG. 5 shows a state in which the rotation is further made 1/4 from there, and the relationship of returning to FIG. The correspondence between FIGS. 2 to 5 and FIGS. 6 to 8 will be described as follows: FIG. 2 → FIG. 6, FIG. 3 → (not shown) FIG. 4 → FIG. The correspondence of the disks is as follows: 7a → 9a, 7b → 10a, 7c → 9b, 7d → 10b, 7e → 9c, 7f → 10c, 7g → 9d, 7h → 10d, 7i → 9e, 7j → 10e, 7k → 9f, 7l → 10f, 7m → 9g, 7n → 10g, 7o → 9h, 7p → 10h.
[0014]
Furthermore, as shown in FIG. 1, a hopper 16 is provided on the entrance side of the carrot automatic supply machine 1 so that the carrot 3 to be supplied is stored. Further, the belt conveyor 17 disposed on the hopper 16 with an ascending slope is for pulling out the carrot 3 from the hopper 16 and transporting it to the automatic carrot feeder 1. That is, it constitutes a preliminary stage of the carrot automatic supply machine 1 and fulfills the function of roughening the carrot 3. An appropriate configuration can be adopted by those skilled in the art, such as providing a perfect endless roller way instead of the belt conveyor 17 and moving the rollers endlessly while rotating each roller. In addition, the return path 6 is divided into a chute 6a arranged at an upper slope at an upper portion thereof and a conveyor 6b arranged at a lower inclination at a lower portion thereof. That is, the chute 6a naturally drops the carrots 3 excluded from the ascending road composed of the first disk group 9 and the second disk group 10, whereas the conveyor 6b forces the carrots 3 with the driving force. Therefore, it is configured to circulate in the hopper 16.
[0015]
Further, as shown in FIGS. 2 to 8, the first disk group 9 and the second disk group 10 are eccentric to the opposite sides with respect to the rotation shafts 7a to 7p. That is, the first disk group 9 and the second disk group 10 are arranged 180 degrees symmetrically about the rotation axes 7a to 7p when viewed from the side. This is because the carrots 3 are conveyed one by one by causing the peaks and valleys formed alternately to appear. As shown in FIGS. 9 (a) to 9 (c), each of the disks 50 constituting the disk subgroups 9a to 9h and the disk subgroups 10a to 10h will be described. Fixing holes 51 and 52 are formed symmetrically, and the above-mentioned rotary shafts 7a to 7p are fitted therethrough so that they can be fixed at an appropriate angle by screws (not shown). . The two fixing holes 51 and 52 are provided as described above so that the first disk group 9 and the second disk group 10 are arranged symmetrically (that is, deviated by 180 degrees) when viewed from the side. This is to facilitate the installation work. Further, as shown in FIGS. 10 and 11, the first disk group 9 and the second disk group 10 are relatively displaced in the axial direction of each of the rotary shafts 7a to 7p as viewed from above. . That is, as viewed from above, the first disk group 9 and the second disk group 10 are alternately arranged at different intervals (displaced) in the axial direction of the rotating shafts 7a to 7p. It is characterized by this. This is arranged in a staggered manner so that the disks of adjacent rotating shafts do not collide (interfer) with each other and the carrot 3 is smoothly conveyed (supplied).
[0016]
Furthermore, there is a feature in the attachment angle of the disk to each rotating shaft 7a-7p arrange | positioned in the center part vicinity of the supporting member 5. FIG. First, as shown in FIGS. 2 to 5, when viewed from the left side, the fifth, seventh, ninth, and eleventh rotation shafts 7e, 7g, 7i, and 7k (disc subgroups 9c, 9d, 9e, and 9f corresponding) about the respective, existing side of the endless chain 12 (counted from the right in FIG. 1), although the first and second disk is attached angles are the same (for example FIG. 10 (1) (2 )), and reference (3) of the third disc is, that different mounting angle of 45 degrees the rotation axis than 1,2 th of the disc, that that is, by declination (e.g. FIG. 10). Further, the fourth disk is characterized by being more deviated by 45 degrees than the third disk (see, for example, (4) in FIG. 10). Third and fourth disk is Attached sequentially retarded with respect to the conveying direction of the ginseng 3 other words. Then, when viewed from the side, the rotating shaft 7f is a 6,8,10-th from the right, 7h, 7j with the respective (disc subgroup 10c, 10d, corresponding to 10e), to the presence of the endless chain 12 side counted from, first to 3-th disc is attached angles are the same (see FIG. 10 for example (1) (2) (3)), the fourth disc is 1, the second disc The angle of attachment about the rotation axis is 45 degrees different, that is, deviated (see, for example, (4) in FIG. 10), and the fifth disk is further deviated 45 degrees more than the fourth disk. It is characterized by being angled (see, for example, (5) in FIG. 10). Than the fourth and fifth disc to the conveying direction (the rotation direction of the rotation axis) of ginseng 3 is attached to retard it in other words. That is, as shown in FIGS. 2 to 5, when the carrot automatic feeder 1 is viewed from the side, when looking at each axis, not all of them appear to overlap, and some of them appear to be shifted. Further, when the carrot automatic feeder 1 is viewed from the side, the disks near the entrance and the exit, that is, the disk subgroups 9a, 9b, 10a, 10b, and 9g fixed to the rotation shafts 7a to 7d and the rotation shafts 7l to 7p. , 9h, 10f, 10g, and 10h have the same mounting angle with respect to each rotating shaft for each disk, and they all appear to overlap when viewed from the side.
[0017]
Therefore, with such a configuration, the carrot 3 is transported straight at the beginning of transportation, but in the middle, part of the carrot 3 supplied in an overlapping manner is pushed laterally and discharged to the return path 6, or By returning a part of the overlapping carrots 3 to the adjacent back valley, the carrots 3 can be supplied to the carrot weight sorter 2 one by one. For example, when three carrots 3 overlap and are transported in one valley, one is flipped laterally toward the return path 6, and one is moved to the back valley so that one carrot 3 is moved. It is possible to transport them one by one. This is particularly effective when the carrots 3 have the same size. Furthermore, at the end of the conveyance path of the automatic carrot feeder 1, the ginseng 3 is conveyed again straight so that the carrots 3 spaced one by one are not accidentally discharged to the return path 6. It is.
[0018]
In addition, although the diameter of each disk mentioned above is 50 (PHI), and the adjacent space | interval of rotating shaft 7a-7p is set to 58 mm, this is not a limited numerical value and can be suitably changed according to a condition. Of course. Further, the total length of the carrot automatic supply machine 1, the carrot weight sorter 2, the hopper 16, and the like is 4500 mm (the carrot automatic feed machine 1 part is 900 mm, the carrot weight sorter 2 part is 2500 mm), and the width is about 600 mm. For example, the interval between the support members 5 is 240 mm and the length is about 800 mm. In addition, the length of the carrot 3 is the range of 30 mm-80 mm normally. In addition, the supply capacity of the carrot automatic supply machine 1 is 6,000 to 9,000 pieces / hour. Since the size of the carrot 3 may vary depending on the type, it can be dealt with by changing the diameter, interval, number, etc. of the disks, the interval of the rotation shaft, the inclination, etc.
[0019]
As shown in FIGS. 1, 10 and 11, the carrot weight sorter 2 is a fork member 20 in which a plurality of hooks are formed instead of a conventional saucer, and a roller 22 is provided at the right end thereof. A pin is provided on the left end of the measurement arm. The fork member 20 is composed of a plurality of bent forks, and is configured to receive and place the carrots 3 supplied from the carrot automatic feeder 1 one by one, and the fork member 20 can pass therethrough. A delivery member 21 provided with a comb-like gap is provided. The comb-shaped delivery member 21 is composed of a plurality of long flat plates erected at predetermined intervals and a short flat plate protruding obliquely upward from the flat plate toward the carrot automatic feeder 1 side. . The carrots 3 are supplied to the delivery member 21 one by one, that is, the carrots 3 move from the carrot automatic feeder 1 while being rolled and are temporarily placed there. By the time the next carrot 3 is supplied, the fork member 20 rises from below, and the fork member 20 scoops up the carrot 3 from below. Accordingly, there is an advantage that the carrot 3 is not easily damaged by the falling impact. As described above, the automatic carrot feeder 1 and the carrot weight sorter 2 are synchronized so that the discharge from the automatic carrot feeder 1 and the timing for scooping up the fork member 20 are matched. As shown in FIG. 1, fixed scales 25 are installed at predetermined intervals on the upper surface side of the carrot weight sorter 2. Further, the carrot weight sorter 2 is provided with a pair of four sprockets 27 at each end of the four rotating shafts 8, and a pair of endless chains 26 are wound around the sprocket 27. . The fork member 20 that has received the carrot 3 is configured to be able to circulate together with the endless chain 26 so that the weight of the carrot 3 can be selected as is well known in the fixed balance 25 (see FIG. 1).
[0020]
Since this embodiment is the invention of the automatic carrot feeding machine 1, the other configuration of the carrot weight sorter 2 is in accordance with the prior art, so that detailed description thereof will be omitted. In addition, instead of the carrot weight sorter 2, those according to the prior art, for example, Japanese Utility Model Laid-Open No. 1-124278, Japanese Utility Model Laid-Open No. 6-48868, Japanese Utility Model Laid-Open No. 4-130227, etc. Of course, it is possible to adopt a weight sorter.
[0021]
The operation of the carrot automatic feeder 1 will be described. As shown in FIG. 12, the carrot 3 is sent from the hopper 16 to the automatic carrot feeder 1 in the direction indicated by the arrow by the belt conveyor 17. The carrot 3 that has moved to the carrot automatic feeder 1 is supplied in an upward gradient from the carrot automatic feeder 1 toward the carrot weight sorter 2 in the direction indicated by the arrow. Here, in the automatic carrot feeder 1, as shown in FIG. 2 to FIG. 5, the mountain and the valley move so as to be realized alternately, that is, when a mountain is formed at a certain place, the adjacent one becomes a valley. . Therefore, even if two or more ginsengs 3 enter the valley, the carrots 3 can be aligned one by one by pushing them out to the return path 6 or returning them to the valley below. Moreover, even if the carrot 3 enters the carrot automatic feeder 1 vertically, it can be aligned so as to lie down. Therefore, the carrot 3 is supplied to the carrot weight sorter 2 from the automatic carrot feeder 1 one by one at predetermined intervals (every predetermined time). Especially when the form, especially the size of the carrot 3 is similar, it is particularly effective and the conventional difficult problem can be solved. The carrots 3 continuously supplied to the delivery member 21 one by one in this manner are intermittently conveyed by the fork member 20 one by one so as to be scooped from below, and as is well known, the carrots 3 are fixed by a fixed scale 25 for weight selection. Are selected for each class. The details of the operation will be omitted.
[0022]
The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and many modifications can be made without departing from the technical idea of the present invention. It is natural that we can do it. For example, instead of retarding several disks and fixing them to the rotating shaft, the support member 5, the rotating shafts 7 a to 7 p, the first disk group 9, and the second disk group 10 descend toward the return path 6. It is also possible to change to a structure that is appropriately inclined (for example, 3 degrees) with a gradient. Moreover, the number of discs, a size, the space | interval of discs, etc. can be changed suitably. The shape, inclination, etc., such as the length, width, and height of the supply path formed by the first disk group 9 and the second disk group 10 can be appropriately changed. Although the first disk group 9 and the second disk group 10 are arranged 180 degrees axially symmetrical to each other, a structure in which the angle and the shape of the peaks and valleys are changed as appropriate is also possible. The degree of retardation of the disk described in the embodiment is 45 degrees, but this can be changed as appropriate, such as 10, 20, 30, 50, 60 degrees, and can be changed according to the situation. It is convenient. It should be noted that the carrot weight sorter 1 can be combined with various weight sorters 2 having various structures, and is highly versatile. Furthermore, in the embodiment, the belt conveyor 17 is provided, but instead of this, a chain conveyor, a chute or the like may be used, or a structure in which the belt conveyor 17 is eliminated may be employed.
[0023]
【The invention's effect】
As described above, the invention described in claims 1 to 3 automates the supply operation to the sorter and reduces the cost by a simple structure, and its industrial utility value is extremely large.
