Description

[Detailed description of the invention] <Field of industrial application> The present invention relates to a box-packing device for spherical agricultural products such as potatoes and onions, which is used to transport spherical agricultural products and pack them into storage boxes at the end of the transport. It is something.

<Conventional technology> Conventionally, when packing spherical agricultural products into boxes, the products were transported by a conveyor and dropped from the end of the conveyor into storage boxes placed on the floor, which caused damage to the agricultural products. I was afraid that if I did, I would get sick.

However, the height of the transport surface of the transport conveyor is set at a height that allows workers to perform work, for example, removing damaged agricultural products, in a posture that does not cause fatigue, for example, approximately 1 m from the floor surface. Due to the height of the storage box, the crops would fall directly to the bottom of the storage box, causing bruises and other damage.

Furthermore, since the worker himself or herself has to feel (measure) the storage volume of the spherical agricultural produce storage box, this not only reduces work efficiency but also increases worker fatigue.

<Problems to be solved by the invention> The problems to be solved by the invention are to carry out and store spherical agricultural products in storage boxes without causing any damage such as bruises, and to electrically control the packing operation. This is done fully automatically, and also by electrically sensing and detecting the volume of agricultural products that matches the storage volume of the storage box.

<Means for solving the problem> The technical means taken by the present invention to solve the problem is to form a shaft frame by connecting a plurality of rollers in series at the front end of the conveyor for conveying spherical agricultural products. Installed and installed a roller conveyor.
The roller conveyor is connected to the supply/stock motor, and a flat U-shaped support frame with a photoelectric sensor attached to the outside of the side wall is installed vertically at the front end of the roller conveyor. A sliding frame with a U-shaped planar shape and vertical holes in the side wall was inserted into the frame so that it could be raised and lowered freely.
A support rod is installed horizontally at the lower end of the side opening of this slide frame facing the roller conveyor side, and a band-shaped curtain with one end edge attached and fixed near the end of the roller conveyor is folded upward through the support rod. At the same time, the other edge of the folded strip curtain is installed on a shaft near the end and is attached to and wound around a winding roll connected to an electric motor, and a damper is installed in the lower opening of the slide frame to swing open and close. At the same time, the damper is pivotally connected to a cylinder attached to the slide frame via a connecting arm, and by supplying spherical agricultural products from the roller conveyor into the slide frame, the photoelectric sensor is placed in a predetermined storage position. The state is sensed and the drive of the supply/stock motor is stopped, and the electric motor is operated to drive the take-up roll, the band-shaped curtain is let out, and the slide frame is lowered to the lower limit position, and the damper is actuated by the operation of the cylinder. The present invention is characterized in that the spherical agricultural products are stored in the storage box arranged on the floor by opening the container.

<Function> In this invention, the spherical agricultural products transported by a transport conveyor are first transported and supplied into a slide frame that is stopped (standby) at the upper limit position by a roller conveyor driven and rotated by a supply/stock motor. Agricultural products having a set volume within a slide frame are temporarily received and stored. At this time, the storage state (storage volume state) of agricultural products being carried into the slide frame is such that a sensor senses and a set volume of agricultural products is received and stored within the slide frame. When the sensor detects that a set volume of agricultural products has been stored in the slide frame, the operation of the supply and stocking motor is stopped, the agricultural products are temporarily stocked on the roller conveyor, and the electric motor starts operating. Then, the winding roll is driven and rotated to let out the band-like curtain and move the slide frame downward to the set lower limit position. When the slide frame moves downward to the set lower limit position, the operation of the electric motor is stopped, the slide frame is stopped at the lower limit position (standby), and the drive source for operating the cylinder starts operating to operate the cylinder. Agricultural products are transported and stored in a storage box placed on the floor while swinging a damper from static in the opening direction. When carrying out and storing the agricultural products into the storage box is completed, the electric motor is activated again to drive and rotate the winding roll, and while winding up (rolling up) the strip, the slide frame is moved upwardly.
When the slide frame rises to a desired position, the drive source operates again to operate the cylinder and swing the damper in the closing direction, thereby closing the lower opening of the slide frame. When the slide frame rises to the upper limit position, the operation of the electric motor is stopped, and the slide frame is stopped (standby) at the upper limit position. When the slide frame stops at the upper limit position, the above-mentioned operating sequence is repeated to carry out and store the agricultural products transported by the conveyor into the storage box placed on the floor. This is done automatically under control.

Further, a through hole 28 is opened in the side wall surface of the support frame 3, and a photoelectric sensor 4 is mounted and equipped on the outside of the wall located in the through hole 28.

The photoelectric sensor 4 detects that when the volume of the agricultural products C received and stored in the slide frame 5 is the storage volume of the storage box E, for example, when the storage volume of the storage box E is 10 kg,
When 10 kg of agricultural products C are carried into and stored in the slide frame 5, this is sensed and a command is given to the electrically linked control panel (Sez shown in the figure) to stop the conveyance and supply of the agricultural products C into the slide frame 5. It acts as a sender.

In the embodiment of the present invention, the sensor 4 is set to operate when a 10 kg agricultural product C is carried into and stored in the slide frame 5. That is, when 10 kg of agricultural products C are stored, the slide frame 5 moves downward and 10 kg of agricultural products C are stored in the storage box E placed on the floor D.
It is set up to carry out and store Kg of agricultural products C.

The slide frame 5 temporarily receives and stores the agricultural products C from the terminal end 1' of the roller conveyor 1, and also prevents the stored agricultural products C from being damaged by bruises or the like in the storage box E placed on the floor D. A metal plate having a desired wall thickness is bent into a U-shape on a plane and formed into a cylindrical shape with one side open like the support frame 3. It is fitted and installed in the support frame 3 so as to be slidable up and down with the side opening 5a facing the conveyor 1 side.

In addition, a vertically elongated through hole 29 is formed in the side wall of the slide frame 5 so that the photoelectric sensor 4 can sense and detect the storage volume state of the agricultural products C received and stored in the slide frame 5, and the side wall is opened. A support rod 30 is rotatably mounted on the lower end of the portion 5a.

This support rod 30 has one edge attached and fixed near the terminal end 1' of the roller conveyor 1, and a hanging strip 6 is folded upward to support and hold the slide frame 5. The support rod 30 is made of metal or hard resin. Formed from wood, etc.

The band-like curtain 6 closes the side opening 5a of the slide frame 5 as the slide frame 5 moves downward to form a cylindrical shape, and also moves the slide frame 5 up and down in cooperation with the winding roll 7. It is. This band curtain 6 is made of highly durable synthetic resin material, cloth, etc., and is formed into a long shape having a width approximately the same as the width of the side opening 5a. The mounting screw 33 is screwed and fixed to the front surface of the mounting plate 31 installed across the space between the mounting holes 12 and 12 via the holding plate 32.

Then, this band-like curtain 6 is folded upward from the inside of the slide frame 5 along the outer periphery of the support rod 30, and the other end is placed on a shaft near the end 1' of the roller conveyor 1, and an electric motor is installed. It is attached and wound around a winding roll 7 connected to a motor 8.

The winding roll 7 is used to move the slide frame 5 up and down by winding up or letting out the strip curtain 6 in conjunction with an electric motor 8, and is mounted on bearings mounted opposite to the lower surface of the machine frame 12 on both sides. A rotary support shaft 35 is installed on a shaft so as to be rotatable between the tools 34 and protrudes from one of the bearing tools 34.
Sprockets 36 and 37 are integrally installed adjacent to each other.

The drive shaft 40 is designed to be activated or temporarily stopped by commands from the control panel.
A sprocket 41 is integrally installed and a roller chain 42 is wound and stretched over the sprocket 36 of the turning roll 7 to connect it.

Also, on the base 39, a command is sent to the electric motor 8 via the control panel to control the raising/lowering stop position of the slide frame 5, specifically, the stop position of the slide frame 5 at the upper limit position at the initial stage of carrying in and storing the agricultural products C (next). The slide frame 5 is lowered to the position where 10 kg of agricultural products C is received and stored (referred to as the first step), and stops at the position (referred to as the second step), and the storage box E is placed on the floor D. Stopping at the lower limit position when carrying out and storing food inside (this will be referred to as the third step), and when discharging and storing 20 kg of agricultural products C into a storage box E with a storage capacity of 20 kg, a 10 kg After carrying out and storing agricultural products C, 10 kg of agricultural products C are transported again.
The slide frame 5, which has received and stored the material, descends again and stops at the position where it is carried out and stored (from the next to the fourth).
An operation order setting device X is installed to stop each of these processes in a set order through mechanical connection with the winding roll 7 and electrical connection with a control panel (shown in the figure).

This operation order setting device X includes eccentric cams x ₁ , x ₂ , x ₃ , ₄ , and a limit switch x 5 that instructs the stop position of each of the above-mentioned steps of _the slide frame 5 to a control panel that is electrically linked through mechanical contact with each of these eccentric cams x ₁ , x _{2 ,} x 3 , and x ₄ . , x ₆ , x ₇ , and x ₈ .

The damper 9 is made by cutting a metal plate into a size that closes the entire lower opening 5b of the slide frame 5, and has mounting protrusions 9a formed upright on both sides of the plate. The rod 10' of the cylinder 10 is mounted and installed vertically on the outside of the side wall of the slide frame 5, and is pivotally connected to the tip of the rod 10' via a connecting arm 45. When the drive source (shown in the figure) of the cylinder 10, which is electrically connected to the control panel (shown in the figure), is operated in response to a command from the control panel, the cylinder 10 is operated to open and close.

Further, a rubber plate 46 is attached to the damper 9 to prevent the agricultural products C carried in and stored from being scratched. In the figure, 47 is a movable plate attached to the inner surface of the side wall of the slide frame 5 so as to be movable up and down while connected to the rod 10' of the cylinder 10.
This movable plate 47 is designed to move upward when the damper 9 swings in the opening direction so that the crops C can be smoothly carried out when being carried out and stored in the storage box E placed on the floor D. When 9 swings in the closing direction, it moves downward.

Next, the operating mode of the box packing apparatus A configured as above when packing 20 kg of agricultural products C into boxes will be explained.The changeover switch provided on the control panel is switched to the 20 kg packing side and the main switch is turned on. Then, the electric motor 8 is activated and the first limit switch x ₅ is activated by contact with the first eccentric cam x ₁ of the operation order setting device X.
is activated and sends a command to the control panel to move the slide frame 5 upward to the first step (FIG. 1). Upon receiving the command, the control panel operates the electric motor 8 to move the slide frame 7 upward. When the slide frame 5 rises to the first step and stops, a command is sent from the control panel to the supply/stock motor 2, which operates to carry and store the agricultural products conveyed by the conveyor B into the slide frame 5. . When the agricultural products C are carried in and stored in the slide frame 5 (as shown by the two-dot chain line in FIG. 1) and the sensing sensor 4 senses and operates, a command is sent to the electric motor 8 via the control panel. When the electric motor 8 receives the command and operates, the second eccentric cam
x ₂ and the second limit switch x ₆ come into contact and send a command to the control panel to lower the slide frame 5 to the second step (Fig. 6). Upon receiving the command, the control panel operates the electric motor 8 to lower the slide frame 5 to the second step and stop it (standby). Slide frame 5
When the sensor 4 detects that 10 kg of agricultural products C is received and stored in the container, a command is sent to the control panel to stop the operation of the supply/stock motor 2. Almost at the same time when the supply/stock motor 2 stops operating, a command is sent from the control panel to the electric motor 8 to start the motor 8. When the electric motor 8 operates, the third eccentric cam x ₃ and the third limit switch x ₇ come into contact and move the slide frame 5 to the control panel.
A command is sent to lower it to the process (Figure 7).
Upon receiving the command, the control panel operates the electric motor 8 to lower the slide frame 5 to the third step and stop it (standby). When the slide frame 5 stops in the third step, the control panel sends a command to the drive source that operates the cylinder 10, and operates the drive source to gently swing the damper 9 in the opening direction. At this time, the movable plate 47 is moved upward so that the agricultural products C can be carried out and stored in the storage box E smoothly.

When the first carrying out and storage of agricultural products C is completed, the control panel operates the electric motor 8 to move the slide frame 5 upward, and when the slide frame 5 rises to the desired position, the control panel operates the cylinder 10.
A command is sent to a drive source that operates the drive source to operate the drive source to swing the damper 9 in the closing direction and close the lower opening 5b of the slide frame 5. Slide frame 5
rises to the first step, repeats the above-mentioned operation, the 10 kg agricultural product C is received and stored in the slide frame 5, and the electric motor 8 is activated by the control panel.
When activated, the fourth eccentric cam _x4 and the fourth limit switch _x8 come into contact and send a command to the control panel to lower the slide frame 5 to the fourth step (Fig. 8). Upon receiving the command, the control panel activates the electric motor 8 to move the slide frame 5 downward, and when the slide frame 5 descends to the fourth step and stops (standby), it activates the drive source to operate the cylinder 10 as described above. By sending a command and swinging the damper 9 in the opening direction, the agricultural products C are carried out and stored in the storage box E.
This completes the packing of kg.

In addition, when packing 10 kg of agricultural products C into boxes, it is sufficient to switch the changeover switch on the control panel to the 10 kg packing side. Activate frame 5 10
Agricultural products C are carried out and stored in storage boxes E that are packed in kilograms.

<Actions and Effects> Since the present invention is constructed as described above, it produces the following effects.

(1) This invention uses electrical control to automatically pack agricultural products transported by a conveyor from the first step of loading and storing them into the slide frame to the third or fourth step of loading and unloading them into storage boxes. Since the packaging is done in a consistent manner, it is possible to improve the box packing work.

(2) The support frame is equipped with a sensor to electrically sense and detect the volume of agricultural products received and stored in the slide frame and then transported to and stored in the storage box, allowing workers to carry out the work themselves instead of using conventional methods. There is no need to weigh (weigh) the stored agricultural products. Therefore, work efficiency can be improved and worker fatigue can be reduced.

(3) By fitting the slide frame into the support frame so that it can be raised and lowered, the bottom opening of the slide frame can be exposed to the storage box placed on the floor, and the slide frame can be transported by the transport conveyor. Agricultural products can be transported and stored to a position where there is no falling distance. Therefore, the agricultural products can be stored in the storage box and packed without causing any damage such as bruises to the agricultural products.

(4) Since the crops transported by the conveyor are temporarily stored on the roller conveyor, the next crop can be quickly fed into the slide frame from the roller conveyor. Therefore, it is possible to shorten the processing time after storing agricultural products in the storage box until the next storage step, and it is possible to provide a box packing device with high processing capacity.
