Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to crushed products such as freeze-dried agricultural products which are fragile and crushed with a small impact, and crushed products having different product sizes or nonstandard products. The present invention relates to a supply device with a sorting function for nonstandard products that sorts and removes and supplies only appropriate products to a packaging line or the like.

[0002]

2. Description of the Related Art Conventionally, a vibration type supply device has been widely used as a means for supplying and conveying a product to a packaging line in the course of supplying and conveying a raw material or a product to a packaging machine, a filling machine or the like. Although not shown, this device cuts to a discharge port along a guide plate provided on the vibration plate while applying vibration in a straight direction to the product placed on the vibration plate. A fixed amount of solid matter can be discharged regardless of the irregular shape, and the flow rate can be easily adjusted by changing the vibration. Further, even if the product is replenished in the supply device during the supply and conveyance, there is an advantage that the flow rate of the product supplied and conveyed from the supply device does not change. Therefore, this vibration type supply device is generally used as a means for supplying products to the packaging machine.
Before the product is supplied to it, the broken or powdered product is removed in advance, so that it is hung on a shifter, which is a so-called sieving machine, and only suitable products are supplied to the supply device.

[0003]

However, even if a crushed product or a non-standard size product is selectively removed by using a shifter before being put into the vibration type feeding device, the vibration type feeding device is
Since a large amount of products are thrown in at once in a random manner, and the product is given a synthetic motion of vertical vibration and longitudinal vibration as a transport principle, it gives a linear motion to the product,
There is a problem that the products are crushed or broken due to collision with each other, and even crushed products and non-standard size products are supplied to the packaging line. In particular, freeze-dried products of agricultural products were fragile, and crushed with a small impact, so cracked products with a bad appearance were apt to occur. Therefore, if these products are packaged, the commercial value is impaired. Therefore, it is necessary to remove the broken products just before filling them in a container or the like, and fill only the appropriate standard products.

The present invention has been made in view of the above-mentioned problems of the prior art, and is a non-standard product for sorting and removing crushed products and non-standard size products of products conveyed and supplied by a vibration type supply device in the supply and conveyance process. It is an object to provide a supply device with a product selection function.

[0005]

[Means for Solving the Problems] The above-mentioned object is an apparatus for selectively removing nonstandard products in the process of supplying products to a packaging process, etc., and stores a large number of products and discharges the products toward a discharge port. A vibrating feeding device, a feeding path is formed between the discharge port of the feeding device and a filling container that fills the product, and a large number of sorting holes are provided in a part or all of the feeding path for dropping a product with nonstandard specifications. It has a punched supply chute with a concave cross section and a brush at the tip to press the bottom face of the selection hole in order to remove the product clogged in the selection hole of the supply chute. A clogging removal device that slides back and forth, a hopper that is provided at the tip exit side of the supply chute and that has an opening / closing lid at the bottom of the hopper that temporarily retains the product, and a hopper that is provided below this hopper to keep the filling container constant. Sequentially provided at each interval This is achieved by a supply device with a sorting function for non-standard products, which is characterized in that the container opening and closing lid of the hopper is opened in synchronization with the arrival of the filling container to quantitatively fill only the appropriate product into the filling container. To be done.

[0006]

According to the present invention, with the above structure, a sorting is performed by forming a transportation path between the discharge port of the vibration type supply device and the filling container, and dropping the non-standard size product being transported onto a part or all of the transportation path. A large number of holes are connected to a supply chute having a concave cross section, and a product clogged in the selection hole is slid with a brush from below the supply chute. Therefore, crushed products and non-standard-sized products that are in the process of being supplied and transported can be dropped from the sorting holes, and only suitable products can be sorted and supplied. Can be supplied to Also, since the clogging of the sorting holes is removed using a brush at regular time intervals, the blocking on the supply chute is released and crushed products and non-standard size products can be sorted and removed stably for a long time.

[0007]

An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an external view of a feeder having a sorting function according to the present invention. In the figure, 1 indicates a supply item, and a supply item 1
Is a raw material or a product (hereinafter referred to as “product”), which may be indefinite or fixed. Particularly, the product 1 is useful for those having physical properties such that it is crushed or broken by a small impact.
That is, even if the nonstandard product is removed by a sieving machine in advance, the unsuitable product generated after that can be removed. Reference numeral 2 denotes a known vibrating type supply device which accommodates the supply product 1 and sequentially discharges the supply product from a predetermined discharge port. In this case, not only a stepped device, a conical device or the like, but also a straight advance type supply device may be used.

Next, 3 is a discharge port 2a of the vibration type supply device 2 and a tray 10 which is a filling container for filling the product 1.
A supply chute that forms a conveying path therebetween is provided at a downward slope toward the downstream side, and the product is transferred downstream by a known vibration device (not shown). Further, in order to select and remove the non-standard-sized products in this carrying path, a mesh-shaped screening net 4 is formed in a part of the carrying path, with a large number of screening holes through which the non-standard-sized products can be fitted. Has been done. In the supply chute 3, a wall for preventing products from falling is erected on the upstream side in the width direction of the conveying path, and side walls for preventing falling are erected on both sides of the conveying path. ing.

Reference numeral 20 is a clogging removing device for releasing the product clogged in the sorting net 4, and a rotary shaft is axially attached to a rotatable mounting member 8 in a direction perpendicular to the conveying path. A large number of elastic bristles are planted, and the tips of the bristles are arranged so that the bottoms of the sorting nets 4 are brought into pressure contact with each other, and the brush 6 extends in the longitudinal direction over the range of the sorting nets 4. And a driving air cylinder 7 that reciprocates.

The reference numeral 5 designates a defective receiving tray for accommodating the nonstandard product 1a falling from the sorting net 4, and the falling product 1
It is made of a container having an area larger than the width and length of the sorting net 4 in order to receive a without leaking.

Reference numeral 9 denotes an openable and closable hopper, which is provided on the outlet side of the supply chute 3 and is arranged on the tray 10 which continuously flows into the packaging line, in accordance with the timing when the tray 10 is directly below the hopper 9. By opening the opening / closing lid 9a provided at the bottom of the product, the supplied product 1 having the standard size can be intermittently introduced into the packaging line.

Next, 11 is a container conveyer conveyor for supplying a tray 10 which is a filling container below the hopper 9 at regular intervals along guides 11b which are erected on both sides with a width interval of the tray 10 therebetween. Then, the tray 10 is pushed by the rear end of the attach 11a projecting from the conveying chain and conveyed.

In the above structure, the product 1 charged in the vibration type supply device 2 is supplied and discharged by the supply device 2 to the supply chute 3 at a constant flow rate. Since the product 1 supplied and discharged is constantly supplied and discharged from the supply device 2,
It is supplied and conveyed toward the outlet of the supply chute 3. At this time, since the supply 1 having the standard product size is larger than the size of the selection hole of the selection net 4, it passes without dropping from the selection hole. However, by making the size of the sorting hole of the sorting net 4 larger than that of the crushed product and the nonstandard product 1a, the crushed product and the nonstandard product 1a fall from the sorting hole when the sorting net 4 passes, and the defective product Collected in the receiving tray 5. Therefore, only the proper product can be supplied to the tray 10. Further, the product stuck in the sorting net 4 is jammed in the sorting net 4 because the driving air cylinder 7 is activated at regular intervals and the clogging removal brush 6 is pressed while rotating from below the entire sorting net 4. Products rise from the sorting holes and are prevented from blocking the transport path.

In the embodiment, the selection hole of the supply chute is described as a mesh net, but it may be a punching metal plate in which a so-called flat plate is formed with holes of a predetermined size. According to this, since there is no unevenness on the transport surface, the product can be transported smoothly.
