Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a simple type TI sorting system that can sort article mold parts and weights at a 1:1 gravimeter ratio by combining a weighing tray support mechanism with a balance type grance scale. It's about machines.

Conventionally, as this type of weight sorting machine, those shown in Japanese Patent Publication No. 46-9748, Japanese Utility Model Application No. 57-14026, and other similar types have been used. In all of these conventionally known weight sorters, the support mechanism for the weighing tray is placed several times above the check 7 for one link of the conveyor chain link plate, so the center of gravity is high or uneven, resulting in unstable running. It had the disadvantage of poor performance and poor scale retention.

In other words, while the size of the saucer exceeds 120 mm, the size of the link plate (cheno pitch) on which the drip tray support mechanism is attached is generally 25.4~25.4 mm.
Since it is 38.1 mm, which is 174 to 1/6 smaller than the size of the tray, the weighing tray support mechanism causes a pitching vibration of f/7 (vertical vibration) in the direction of conveyor movement, resulting in a "r-head deck" against the mounting seat. The vehicle could not run stably and performance could not be improved.

There are also some sorting machines that combine a spring scale as a weighing device, but these are important because they are an analog type that uses one point of spring tension for sorting at M stage.

It is extremely difficult to set and the tension (
Since the weight (t) changes, it is easy to handle.

In order to eliminate these drawbacks, the present invention improves the running stability of the saucer support mechanism, simplifies the saucer support member vertically, and improves the accuracy of Nl acid. The purpose of this is to obtain a simple, easy-to-handle multi-position sorting machine that can digitally set iN and S4 using weights with a 1:1 ratio, and uses the following technical means. be. A large number of underframes are installed at predetermined intervals in a transfer device that runs and rotates endlessly. A vertical support mechanism for the tray is placed in the center of the nuclear underframe to prevent empty load from acting on the tray, and fixed fulcrums are placed above and below the front end of the underframe. A weighing tray support mechanism is constructed by providing floating fulcrums at two locations of the receiving IIn support member facing this and connecting them in a parallelogram shape with upper and lower stays to prevent the tray support member from falling over and to move it up and down. A sliding piece is provided at the lower end of the saucer support member protruding below the underframe to form a running body.

On the other hand, a balance type balance scale is constructed by attaching a weight plate to the vertical support rod on one side of the balance scale that forms the Loppal mechanism, and attaching a measuring rail to the vertical support rod on the other side, and attaching the above-mentioned traveling side on the measuring rail. A weighing and sorting pass device is constructed by combining sliding pieces of weighing bodies in a running manner, and weighing and sorting the articles based on the gravimetric ratio between the articles on the receiving tray and the weights on the weighing pan. ′
□In the present invention, the length of the stay of the tray support mechanism and the length of the balance arm of the balance scale are made equal to each other by the configuration as described in 1. When we weigh the ratio of 1:1, we get . Therefore, to set the weight for sorting and sorting, you only need to place a weight equal to the standard value. In other words, if the weight is reduced by 9 to 1 g, an extremely simple and easy-to-handle stack sorting machine can be obtained that can digitally adjust the sorting time in 1 g increments.

In addition, the present invention has the underframe of the weighing tray support mechanism formed to be large in proportion to the size of the tray, and the vertical tray support mechanism is placed in the center of the underframe so that the load of the tray acts, and the underframe is connected to the tray support member. Attach it to the transfer device in two places, front and back, so that it sits horizontally.
The weighing pan support mechanism was constructed by connecting the fixed fulcrums provided at the top and bottom of the front end of the underframe to the top and bottom stays, respectively, with the tray support members to form a parallelogram. The horizontal line connecting the mounting parts and the vertical tray support member with the tray 111N on the top and the sliding tongue on the bottom are transported so that the center of gravity is stabilized and horizontal and vertical vibrations (pitching vibrations) are prevented during travel. ) It is possible to sort out the grains with high precision without inducing any problems, and at the same time, it can run stably even at high speeds, further improving performance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Diagrams showing embodiments of the present invention will be described below.

2 is a sorting machine frame, 2 is a chenor rail, and 3 is a compare chain as a transfer device.

Sorting machine frame il: formed into a straight conveyor type,
They are formed depending on the shape of the various sorting machines, such as those formed in a circular shape and those formed in an oval shape that travels and rotates on a flat surface. In the case where the sorting machine is a round sorting machine that rotates in a circular manner, the compare chain 3 may be replaced with a rotating body and used as a transfer device W.

4 is the odometer companion, and the underframe 5 is used as the pace JIJ1
6, saucer support member 7, sliding tongue piece 8, and upper and lower stays 9.9
The main chapters are organized as follows.

The underframe 5 is proportional to the planar size of the saucer 6, and is formed into a square frame shape as shown in FIG. 9, and has a front end horizontal frame 5a.
upward and downward protrusions 5b and 5c are formed at predetermined rlj, and fixed fulcrums 10° and 10a are provided respectively, and the left and right side frames 5d and 5e have a traction mounting part 11 on the front side and a horizontal holding part on the rear side. A mounting portion 12 is provided. The traction mounting part 11 is rotatably attached to the front mounting bracket 13 provided on the link plate of the compare chain 3, and the horizontal holding claw (=J part 12 is a mounting bracket with multiple links from the front mounting bracket 13). 13
It is formed so that it can be slid back and forth on a. The distance between the front towing attachment part 11 and the rear horizontal holding attachment part 12 is widened to several times the size of the tray within the range of the size of the saucer, so the underframe 5 has a good seat and is suitable for commercial transportation. It's stable though. In addition, the horizontal holding area 12 on the rear side has a shape (elongated hole) that allows it to slide slightly back and forth relative to the mounting bracket 13a, so the chino becomes arcuate when returning with the sprockets at the tip and rear end of the conveyor. Even if the straight-line distance between the front and rear mounting brackets 13.13a decreases due to this, the device rotates smoothly without any trouble. A rear horizontal frame 5f of the underframe 5 is formed so as to attach a cam 14 for tilting the saucer 6.

The saucer support member 7 is attached to the front end of the underframe 5 at the vertical intermediate portion.
Lower fixed fulcrums 10, 1 (symmetrical to 1a -E lower floating fulcrums 15 * 15 a are inserted vertically through the center of the underframe 5, and the above fixed fulcrums 1 are fixed by stays 9.9.
0.1Oa and the floating fulcrum 15.15a are connected at the top and bottom, respectively, and a parallelogram with centers of 4"Ik is drawn as t1".
A running roller 16 and a sliding tongue piece 8 are attached to the lower part. The traveling rollers I6 run on the roller rails 17 while supporting the tray support member 7 at a height where the stays 9.9 are horizontal during the transfer process of the article supply section or the like. Sliding tongue piece 8
is mounted horizontally on the side opposite to the roller 16, is shaped like an auxiliary plate, has a sharp front end like a knife blade, and slides over the measurement 1/-rule 247 of the balance 19, which will be described later.
It has the function of N sorting.

The saucer 6 is attached to the upper part of the saucer support member 7, which is directly connected to the center of the underframe 5 with stays 9, 9, so that it can tilt to one side with a saucer pin 18, and when the stay 9°9 is in a horizontal state. During a normal transfer process, the weighing body 4 is held horizontally and has a stable load supporting mechanism, that is, a robo-guru mechanism.

19 is a balance scale, which includes a balance 20, a stay 21, and a fulcrum 2.
2. Three vertical members 2 provided at emphasis points 22a and 22b
3.23a and 23b are the main components to form a donkey pal mechanism, the measurement rail 24 is attached to the upper part of the emphasis vertical member 23a, the weight plate 25 is attached to the emphasis vertical member 23b, and the fulcrum vertical member 23 is mounted on the stand 26. It is supported on a base 27 to constitute a balance type balance scale. Each vertical part of the fulcrum 22, the emphasis 22a1 and the power point 22b 23, 23a
.

23b uses the same parts to eliminate variations in the vertical distance between the balance 20 and the stay 21 to improve accuracy.

Distance t between fulcrum 22 of balance 20 and point 221L and fulcrum 2
2 and the force point 22b are the same arm length on a one-to-one basis, and the arm lengths t of the upper and lower stays 9.9 that support the tray support member 7 of the traveling measuring body 4 are also the same on a one-to-one basis. The length is important.

Reference numeral 28 denotes a stock bar, which is installed below the force point 1+11 of the balance 20 to keep the balance 20 horizontal and prevent the measuring rail 24 from rising above a predetermined height. Reference numeral 29 denotes a spring, which causes the balance 20 to tilt when a load is applied to the measuring rail 24 at the focal point 22a through the sliding tongue 8, and then restores itself when the load is removed and returns to its original position, and causes the balance to spring back as the speed increases. This prevents vibration.

Furthermore, this spring 29 also has the function of equalizing the weight 25 of the balance scale 19 so that it becomes zero when the tray 6 of the traveling measuring body 4 is empty.

A transport device for endlessly running and rotating the balance scale configured as described above. Traveling weighing bodies 40 are mounted at slightly equal intervals. The sliding tongue piece 8 is placed at the bottom of the traveling path and protrudes below the center of the traveling measuring body 4. However, the measuring rail 24 of the balance scale 19
The weighing section and sorting device constitutes a device in which the weighing section and the sorting section are combined so as to slide at the same distance from the fulcrum.

Hereinafter, the operation of the weighing and sorting apparatus will be explained. For example, when sorting items into items whose weight exceeds 1,501 g and items whose weight is 1.50 g or less, in other words, when sorting and sorting, the claw l is 15
When set to 0I, add 1 to the weight 111125 of the balance scale 19.
A weight of 50 g is placed in the transport device, and when the article to be sorted is placed on the tray 6 of the traveling body 4 and the article is run, when the sliding tongue piece 8 comes onto the measuring rail 24. Compare the weight of the item and the weight of the weight using a balance (check the balance). If the weight of the article is 152g, the load W1 applied to the point 22a is the force P (weight type Ii150
g) Since the balance Id of the balance 20 is larger, the balance 20 is shifted and the measuring rail 24 sinks, so the sliding tongue piece 8 is sorted below the separate needle 30 provided on the exit side of the measuring rail 24. The sliding tongue piece 8 guided below the separate needle loses its support, so the tray support member 7 falls downward in a vertical position, and the tray 11116 tilts to one side using the cam 14 and the tray bin 18 as a fulcrum to hold the article. On the other hand, if the weight of the article is 149 I, the load W2 applied to the point 22a is smaller than the force P applied to the point, so the balance 20 is tilted. 1 passes, so it travels t: 1 lfi body 4 saucer 6
is held horizontally for one meter, and the article passes through it without being ejected. The mechanism for sorting with this separate needle is the same as that of the above-mentioned known method.

If the item of goods changes and the sorting standard is changed, the sorting and sorting will be done by Party A (
For example, if 0'' is 165!jK#, add 15g to the weight pan to make a 165g weight.''Similar to item 2, if the item is 1679 or more, 1 will be ejected, and if the item is 164.9 or less, it will pass through without being ejected. do.

According to the actual Mlj example, the above-mentioned known one is classified as Higashi H120.
The error for M is ±4g or more -E (2/100~3/It
) O), whereas the product of the present invention had a weight within ±2 g (1
/100), making it possible to significantly improve performance.

As described above, the present invention is designed such that the underframe of the traveling 84'414 body is formed to be large in proportion to the size of the receiving tray, and the two places on the front and rear are mounted with mounting brackets to sit horizontally on the transfer device. After a few steps, the saucer support member was placed vertically through the central part of the base frame, and horizontal stays were placed above and below the mounting part of the underframe to form a parallelogram of the mouth/gu-pal □ mechanism. Therefore, the weight 13 was stabilized, and even when running at high speed, there was no vibration that would interfere with the counting accuracy, and the sorting performance was significantly improved.

The present invention also provides a length t of a stay that prevents the tray support member from falling and has the function of a donkey pal mechanism, a point of gravity that receives the weight of the tray of the balance scale, a pressure point between fulcrums AIF t, and a force point and a fulcrum that receive the amount of the weight wheel. Since the sliding weighing device is configured with a lever ratio of 1:1:1 and the distance t is the same, it is possible to balance the small amount of articles on the tray and the amount of the weight wheel of the balance on a 1:1 ratio. Ta.

Therefore, an extremely simple weight sorting machine that can digitally set the sorting weight by adding and removing weights has been obtained.

Another feature is that a cam is used to tilt the receiver +++1, so as the receiver tilts, the contact point between the receiver and the cam changes from O→1→2 as shown in Figure 12 (a) and (b). As shown by X, the saucer support member sinks as it moves toward the saucer bin side F
, ij Y can be decreased to tilt the saucer. Therefore, when the traveling weighing body travels, the influence of vibration caused by the vertical movement of the tray is reduced, and the sorting accuracy can be improved.

City...Sorting machines use scales - In order to improve accuracy and capacity, electronic scales, etc. are used, and the present invention is extremely effective as described above, in contrast to those that are moving toward multiple scales, can edges, and high prices. The L1-shaped structure is designed to provide good running stability necessary for a singing fan, thereby improving accuracy and performance, and at the same time providing a +VI easy-to-use high-performance heavy-duty sorting machine that can be manufactured at a low cost. The economic effects are significant.
