Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is designed to take out products such as spherical confectionery, which are relatively irregular in size and shape, one by one and send them at regular intervals to the next process, which are sent randomly by a medium-sized conveyor. This invention relates to an automatic feeding device.

For example, when packaging a frozen confectionery called "Chou Ice Cream," which is a spherical cream puff pastry filled with ice cream, the naked products are randomly sent by a medium-sized conveyor and placed one by one into a packaging machine for a set period of time. Supplied at intervals,
This is done by pulling out a film of polypropylene or the like wound into a roll, feeding it at regular intervals into a cylinder, heat-sealing the front and rear parts, and cutting. However, since these sweets are relatively fragile, have relatively irregular shapes and dimensions, and have uneven surfaces, when mechanizing the supply of products to packaging machines, for example, the products are temporarily stopped with a stopper and the stopper is released. It was difficult to find a way to take the timing, and if the next product collided with the stopper due to line pressure after sending out one product, there was a risk of damage to the product, which hindered mechanization. For this reason, the product supply to the packaging machine was carried out exclusively by hand, which had the disadvantage of not being able to process at high speed, being inefficient, and increasing labor costs, resulting in high costs. This invention is based on the above-mentioned method, in which products such as spherical confectionery of relatively irregular size and shape are taken out one by one, which are sent randomly by a medium-sized conveyor, such as the supply of first-class confectionery such as Shoe Ice to a packaging machine. The object of the present invention is to provide a product feeding device that can automatically feed products at high speed without damaging the product when feeding at regular intervals. An embodiment applied to a supply device will be described in detail with reference to the drawings.

As shown in FIG. 1, this apparatus is provided with a wide conveyor 2 for carrying out spherical product boxes at random, followed by a chute 3 which is inclined so that the carrying direction is downward.

The chute 3 is used to convey the amount of products fed from the wide conveyor 2 during the stop time of the packaging machine (for example, the time required to change the roll of packaging material (film) or remove the product if it gets caught in the seal cutter). The downstream end of the chute 3 is provided with a plurality of deep notches 3a in the shape of comb teeth. A rotary impeller 4 having a rotating shaft in a direction perpendicular to the discharge direction is provided.The rotating impeller 4 is driven to rotate intermittently in the direction of rotation indicated by an arrow in the figure by a drive device (not shown). a, and 4 round rod-shaped blades arranged in four radial rows around the periphery at intervals of 900 mm, each row having a number corresponding to the notches 3a of the sheet 3. b has a size and position that allows it to easily pass through the notch 3a during rotation.The length of the blade 4b is shorter than the size of the product to be conveyed.The chute 3 of the rotary impeller 4 A belt conveyor 5 is provided parallel to the axis of the impeller 4 on the opposite side.A pair of guides 6 are provided in parallel on both sides of the upper surface of the conveyor 5 with the upper side open.Guides 6 The position of the upper end is located on the extension line of the chute surface of the chute 3, and the width of the conveyance path on the upper surface of the conveyor 5, which is limited by the guides 6 on both sides, is such that the finished products are lined up in a single line. The width of the conveyor 5 is set to allow smooth conveyance.The conveyor 5 extends slightly further downstream than the range of the rotary impeller 4, and has a short chute at its exit.
is connected to a storage conveyor 8 which is provided perpendicularly to the conveyor 5. A pair of parallel guides 9 are provided on both sides of the storage conveyor 8, and the conveyance path width on the upper surface of the conveyor 8, which is limited by these pair of guides 9, allows the products 1 to be smoothly conveyed side by side. The width is set to an appropriate width for As shown in detail in FIG. 2, the conveyor 8 has a collar 11 mounted around a rotating rod 10 that is constantly rotating at a constant speed in the direction of the arrow by a drive device (not shown).
A large number of slip rollers covered with
A slip that causes the product 1 placed thereon to move forward, and when it comes into contact with a preceding product and restricts its conveyance, slips between the two members 10 and 11 to prevent an increase in line pressure. A roller type conveyor is used. Further, the conveyor 8 can change its speed to match the supply capacity to the packaging machine. At the tip of the storage conveyor 8, there is a
After the plate 13 is fixed and conveyed on the conveyor 8, a stopper 14 is provided in front of the product that is pushed out onto the plate tortoise 3 and placed on the platform.

The stopper 14 is supported at its upper end, and is configured to swing a certain distance in the conveyance direction of the conveyor 8 by a solenoid 12. Two air guns 6 are provided on the sides of the product at a position where it comes into contact with the stopper turtle 41 in the backward position (in the forward direction as seen from the conveyor 8). The air gun amount 5 is designed to instantaneously inject a jet of air by opening the electromagnetic valve 6 and supplying high pressure air to push out the product laterally.On the side facing the air gun 5, a guide 9 is installed. The open chute 87 is provided perpendicularly to the storage comper 81 and continues to the receiving port of the packaging machine conveyor turtle 8. Since this device is configured as described above, the chute 87 is randomly unloaded from the wide conveyor 2. The product 1 is stored on the chute 3.

The chute 3 has sufficient storage space to store the amount of product to be carried out during the time when the packaging machine is stopped. Even if the intermittent drive of the wheel 4 is stopped, there will be no overflow.An example of the top of the product 1 in the storage state is that the rotary impeller 4b on the lower side has the iron in the notch 3a, as shown in detail in FIG. The tip of the chute 3, which is in the recessed state, is held in place with its front side in contact with the preceding blade row.The rotary impeller 4 rotates in the direction indicated by the arrow at a rotation pitch commensurate with the throughput of the packaging machine. The product 1 in the highest row on the chute 3 is rotated intermittently by 900 times each time, and the product 1 in the highest row on the chute 3 is
b, falls onto the conveyor 5, is conveyed in a single line, and is sent out through the chute 7 toward the storage conveyor 8. The next intermittent rotation of the rotary impeller 4 is not performed until the last product leaves the range of the rotary impeller 4, so that the next product is placed above the head of the product being conveyed on the conveyor 5. The product will not fall and cause damage. The products sent to the storage conveyor 8 are regulated by guides 9 on both sides and conveyed in a single line.
When the first product comes into contact with the stopper 14 and stops, the following products are stored in a line with their front and back in contact with each other.

The first one of the products stored on the conveyor 8 is pushed out by the following products and placed on the plate 13, and the front end hits the stopper 4 and stops.

The packaging machine sends signals at regular intervals,
When the solenoid 12 operates and the stopper 14 retreats, high-pressure air is sent to the two side air guns 15 via the electromagnetic valve 16, and the product 1 is quickly moved laterally by injecting an instantaneous air jet. It is pushed out, passes through a chute 17, and is fed into a conveyor 18 for a packaging machine.
The stopper 14 immediately returns to its original position after retracting, and stops the next product pushed onto the plate 13. At this time, since a slip roller type conveyor is used as the conveyor 8, large line pressure is not generated even if the products are in contact with each other, and the products are moved to the stopper 1.
There is no possibility of damage caused by sudden collision with 4. In addition,
The storage conveyor 8 is safer because it can change its speed to match the supply capacity to the packaging machine.

As described above, the products are automatically fed one by one to the packaging machine conveyor at a high speed at regular time intervals.

This invention is not limited to supplying products to the "Shoe Ice" packaging machine of the embodiment, but can also be applied to products such as fragile, spherical confectionery with relatively irregular shapes and dimensions that are sent randomly on a medium-sized conveyor. It can also be effectively applied to supply apparatuses for various purposes that take out pieces one by one and feed them to the next process at regular time intervals.

As described above, according to the present invention, it is possible to automate and speed up the supply of products such as spherical confectionery at regular intervals, resulting in remarkable improvements in work efficiency, product progress, and cost reductions due to labor savings. Effects can be obtained.
