Description

[Detailed Description of the Invention] <Technical Field> The present invention stores thousands or tens of thousands of types of seed bags for each product, and automatically supplies the necessary types and quantities according to customer orders. The present invention relates to an automatic seed bag feeding device that performs seed bag feeding one after another.

<Prior Art> There are approximately 30,000 types of seed bags, approximately the size of postcards, which are sold at flower shops, seed shops, and gardening shops, containing seeds of vegetables, flowers, etc. Furthermore, because the amount of seeds to be sealed differs even for the same seeds, the number of seed bags can be several times larger. During the peak season, more than 1,000 kinds of seed bags are ordered, and there are many varieties where only one bag of Tatsuta is ordered per day.

Traditionally, companies that supply these seed bags to flower shops, seed shops, and gardening centers across the country store thousands or tens of thousands of types of seed bags, stacked by product, on square-shaped shelves.
With a large number of workers on hand, they select the necessary types and quantities of seed bags from the sorting shelves to meet various customer orders, pack them, and ship them. For this reason, labor costs are enormous and space is required, and mechanization and
Automation is a problem.

<Object of the invention> The present invention was devised in view of the above points, and
To provide an automatic seed bag feeding device that stores thousands or tens of thousands of types of seed bags for each product and automatically feeds the required types and quantities according to customer orders.

<Structure of the Invention> The automatic seed bag feeding device of the present invention is capable of storing seed bags in a stacked manner, and is configured such that the seed bags can be taken out in order from the lowest seed bag through the adjustable seed bag outlet on the front side of the peripheral wall. A row of stock cases is formed by arranging a plurality of stock cases side by side, and a bottom seed bag is stocked in any stock case by being selectively operated by a clutch provided at the bottom of each stock case. A seed bag delivery means is provided on the front side of the seed bag outlet of each stock case and is provided in front of the seed bag outlet of each stock case and rotates in contact with each other to move the seed bag through a notch formed in the bottom wall of the case and move the seed bag to project the seed bag as required. Seed bag pulling means consisting of a pair of upper and lower rolls that pull out and drop the seed bag projected from the seed bag outlet by the seed bag sending means; A first belt conveyor receives and places seed bags falling from the stock case by the feeding action of the bag pull-out means, and operates for a certain period of time after the seed bag feed-out means and the seed bag pull-out means stop operating, and the first belt conveyor conveys the seed bags. A chute is installed at the end of the chute to receive the seed bags being conveyed and guide them to the desired position by gravity, and a bucket is installed at the lower end of the chute at a desired position to guide the seed bags falling from the chute to the desired position. There is a bucket conveyor that receives seed bags into the bucket that fall one after another by stepping one pitch at a time, and a bucket conveyor that is installed at the conveying end of the bucket conveyor and is conveyed by the bucket as the bucket falls over. A second belt conveyor is installed near the second belt conveyor, which receives and carries seed bags to the required position, and a bucket conveyor, and prints documents such as delivery notes and invoices corresponding to the seed bags stored in each bucket. It is characterized by consisting of a printer that cuts and drops the cut into a bucket.

<Example> Hereinafter, an example of the automatic seed bag feeding device of the present invention will be described with reference to the drawings together with the seed bag.

First, I will explain about the seed bag. Generally, seed bags are
It has a small rectangular shape as shown in FIGS. 2a, b or 3 a, b. The seed bag F shown in Figures 2 a and b is made by stacking two sheets of seed bag paper, closing three sides, and then closing the other side after putting the seeds in. Generally, it is used when the seeds are small and the amount is small and does not take up much space. used. Figure 3a,
Seed bag F in b is made by folding a sheet of seed bag paper in the middle, closing two sides, adding seeds, and then closing the other side.
This is used when the seeds are large or small but are bulky. For convenience of explanation, the closed portion will be referred to as the ear, and the thick portion that accommodates the seeds will be referred to as the body.

Next, regarding the automatic seed bag feeding device, see Figures 1 and 4.
This will be explained with reference to FIGS. 5, 6, 7, 8, and 9.

Fig. 1 is an overall schematic diagram of the automatic seed bag feeding device, and there are four stock case groups in which groups A and B, and groups C and D face each other, and each stock case group has stock case 1 arranged in a horizontal row. The seed bags stored in the stock cases 1 of stock case groups A and B and the seed bags stored in the stock cases 1 of stock case groups C and D correspond to each stock case 1. The provided seed bag delivery means 2 and seed bag withdrawal means 3 feed the seed bag onto the first belt conveyor 4a or 4b, respectively, and pass through the chute 5a, 5b to the bucket conveyor at a required upstream position of the bucket conveyor 6. Falling to 6a, 6
It merges with documents such as delivery notes and invoices that are printed and cut off by the printer 8 at position n, and is then fed onto the second belt conveyor 7, where the two are manually cut off at the end of the second belt conveyor 7. Seed bags are checked against documents such as delivery notes and invoices, and then the seeds are packed into bags.

To explain in detail below, FIG. 4 shows a perspective view of the main parts of two stock case groups in which corresponding stages of a three-stage stock case row face each other, and FIG. 5 shows an enlarged view of the main parts. A partial perspective view is shown. Furthermore, Figure 6 shows that
Thin seed bag F shown in Figure 2 is placed in stock case 1.
1, F2, . . . are shown in a vertical sectional side view, FIG. , . . . are shown in a vertical cross-sectional side view, and FIG.

As can be seen from FIGS. 6 and 8, the stock case 1 has a rectangular horizontal cross section that is slightly larger than the seed bag, and includes a front wall 11, left and right side walls 12, 13, a rear wall 14, and a bottom wall 15. The bottom wall 15 is inclined by about 5 degrees so that the front side is lower, and the front wall 11 and the rear wall 13 are parallel to each other and tilted backward by about 15 degrees, so that the seed bags F1, F2, . . . are slightly shifted. The seed bags are stored in a stacked manner so that the load of the second and subsequent seed bags on the bottom seed bag is kept small, and the tightness between the bottom seed bag and the second seed bag increases. It is made to be sufficiently small compared to the sending force of the sending means 2. And stock case 1
is equipped with a seed bag outlet on the front wall 11, and the bottom wall 1
5 has a cutout 18, and the rear wall 13 has a wide slit 19 extending from the top end to the bottom end. For the exit of the seed bag, the upper part of the opening 16 cut out in line with the lower end of the front wall 11 is connected to the opening adjusting plate 17.
The notch 18 allows the rubber body 22 of the seed bag delivery means 2 provided below to feed out the lowest seed bag F1 in the stock case. The slits 19 are wide and wide from the top and bottom to ensure that the stock condition of the seed bag can be seen from the rear of the case so that the stock can be adjusted and the remaining stock can be checked. The upper ends of the side walls 11, 12, 13 are each bent outward and have a guiding function to facilitate stacking and storing of seed bags. Then, fitting rails 111, 111 are fixed to the left and right sides of the bottom wall 15, and the front end of the bottom wall 15 is placed on the rear end of a pair of corresponding mounting plates 112, 112 on which each stock case 1 is placed. When the fitting rails 111, 111 are slid forward, the pair of mounting plates 112, 1
12 and comes into contact with the stopper 113, and then the stock case 1 is fitted onto the pair of mounting plates 112, 1.
12 so that it cannot be lifted up.

As can be seen from FIGS. 5 to 9, the seed bag delivery means 2 has a common rotation shaft 23 provided at the bottom of each row of stockcases, and a common rotation shaft 23 provided at the top of each stockcase group. A motor 26 that rotates the three common rotating shafts 23 at the lower stage, and a clutch 24 provided corresponding to each stock case 1.
, a rotating disk 21 that rotates when the clutch 24 is turned on, which is attached to each clutch 24 so as to rotate freely about the common rotating shaft 23; It consists of a rubber body (seed bag delivery tool) 22 and a positioning means 25 for positioning the rotary disk 21 at a fixed position. The timing belts 27, 27 are connected to the output shaft 2 of the motor 26.
The rotation of 6a is transmitted to three common rotating shafts 23. The motor 26 is adapted to be driven when it becomes necessary to feed a seed bag from at least one stock case in the stock case group. One or more clutches 24 that require the seed bag to be fed are turned on at the same time, and the phototube switch 27 shown in FIGS. When the number of bags is counted, it will turn off again.
For this reason, the rubber body 22 protruding from the rotating disk 21
enters into the stock case 1 through the notch 18 opened in the bottom wall 15 of the stock case 1 along with the rotating disk 21, and while slightly lifting the bottom seed bag F1, it is pinched by the seed bag pull-out means 3 due to contact resistance. It is now being sent to a certain place.

As can be seen from FIGS. 5 to 9, the seed bag drawing means 3 corresponds to each stock case 1 so that a pair of left and right upper rolls 32 are placed on a pair of left and right lower rolls 31. Lower roll 31 and upper roll 32
is formed with a rubber layer on the outer periphery to maintain feeding friction force. The pair of upper rolls 32 are
Rolling pressure is applied to the lower rolls 31 by springs 36, 36, which are attached to a floating shaft 35 provided for each stock case so as to rotate along with the pair of lower rolls 31, and are tensioned to pull both ends of the floating shaft 35 downward. is added and can escape upward. All the pairs of lower rolls 31 are fixed to three common rotating shafts 33 provided corresponding to the upper, middle, and lower stock case rows of each stock case group, respectively, so that the intervals can be adjusted freely. Common rotation axis 3
3 is connected to the common rotating shaft 23 of each corresponding stage via a timing belt 34, and is rotated using the motor 26 provided for each stock case group as a common drive source. The upper end of the roll substantially coincides with the bottom wall 15 of the stock case 1. The horizontal floating shaft 35 has both ends fitted into a pair of vertical shafts 37, 37, and is guided in the vertical direction while remaining horizontal.
is pulled downward. Thus, when the seed bag is sent out by the selectively operated seed bag sending means 2, the seed bag drawing means 3 pulls out the seed bag so as to sandwich it and roll it into the first belt conveyor 4a or 4b.
drop it on top.

As shown in FIG. 6, the seed bag pull-out means 3 pulls thin seed bags F1 and F shown in FIG. 2 into the stock case 1.
2,... are stacked and stored, as shown in Fig. 7, the distance between the pair of lower rolls 31 and upper rolls 32 is adjusted greatly so that they can be pulled out by sandwiching the left and right ears of the seed bags. In addition, the opening adjustment plate 17 of the stock case 1 has hanging stopper portions 17a and 17b at both corners of the lower end that escape the body of the second seed bag F2 from the bottom and come into contact with the front ends of the left and right ears. The bag F2 is prevented from coming out together with the first seed bag F1. In addition, as shown in FIG. 8, when the thick seed bags F1, F2, . . . shown in FIG. The distance between the pair of lower rolls 31 and upper rolls 32 is adjusted to be small so that the required middle part (body) of the left and right side of the seed bag can be pulled in and pulled out. It is used in reverse, that is, the stopper parts 17a, 17
The seed bag F2, which is the second seed bag from the bottom, is held at the front end of the body by the lower end of the plate, which is mounted so that b is on top and has both corners cut and is smooth.

The first belt conveyors 4a and 4b are provided below between stockcase groups A and B and between C and D, where three stockcase rows face each other. The first belt conveyor 4a, 4b
is operated for a certain period of time after the seed bag sending means 2 and seed bag pulling means 3 of the corresponding stock case groups A and B or C and D are stopped, and transports the seed bags by a length slightly larger than the stock case row. Shoot 5
a and 5b are first belt conveyors 4a and 4, respectively.
The lower ends of the chute 5a, 5b correspond to the bucket 6a at a required upstream position of the bucket conveyor 6 installed below. The bucket conveyor 6 includes a first belt conveyor 4a,
After the operation of 4b is stopped, the operation is performed in steps of one bucket pitch at a time. The second belt conveyor 7 is installed below the conveyance end of the bucket conveyor 6 in a direction perpendicular thereto, and is carried out for a certain period of time after the bucket conveyor 6 stops operating, and conveys the seed bags to the conveyor end. The printer 8 is located above the bucket 6n at a required downstream position of the bucket conveyor 6, and prints documents such as delivery notes and invoices on the bucket 6n.
Separate and drop to n.

Next, the action will be explained.

It is now assumed that different seed bags are stored in each stock case 1 of each group. Then, the order details written on the order slips mailed from customers in each region, namely the orderer's name and address, and the product number and quantity of the seed bags, are entered into the personal computer. Then, in this device, seed bags of various product numbers and quantities written on the order slip are simultaneously and selectively fed from the stock case groups A, B, C, and D onto the first belt conveyors 4a and 4b, and 5a and 5b, and are collected in a lump into the bucket 6a of the bucket conveyor 6, where documents such as delivery notes and invoices printed by the printer 8 are dropped and transferred onto the second belt conveyor 7. The seeds are then manually checked against the seed packets and documents, and then packed into bags.

For example, according to the order details on a personal computer, 10 seed bags are stored in stock case 1 at address m in the lower row of group A, and 10 seed bags are stored in stock case 1 at address n in the middle row of group A. 2
Bag and stock case 1 at address o in the lower row of group B.
Input 5 bags of seeds stored in , and 3 bags of seeds stored in stock case 1 at address q in the upper row of group D.

In this way, when there is an input on the personal computer, it means that groups A, B, and D have been selected, and that each row and each address mentioned above has also been selected at the same time. Then, the motor 26 of group A operates until feeding of 10 bags is completed, the motor 26 of group B operates until feeding of 5 bags is completed, and the motor 26 of group D operates until feeding of 5 bags is completed.
rotate for a predetermined time until feeding of three bags is completed. Therefore, along with this, A, B,
All the common shafts 23 and 33 of group D rotate, and all the lower rolls 31 of groups A, B, and D rotate.
will rotate, but in the seed bag delivery means 2, only the clutches 24 of each stage and each address mentioned above are turned on at the same time.
Therefore, selective rotation is performed to deliver the seed bag.

That is, the seed bag delivery means 2 at address m in the lower row of group A rotates 10 times, the seed bag delivery means 2 at address n in the middle row rotates twice, the seed bag delivery means 2 at address o in the lower row of group B rotates 5 times, and group D The seed bag delivery means 2 at address q in the upper row rotates three times. In this way, after completing each rotation,
Each of the selected clutches 24 is returned to OFF. As can be seen from the above, if two or more addresses are selected in the same group, motor 2 of that group
6 is rotated as required according to the largest number of pieces to be fed.

Therefore, each time the rubber body 22 of the seed bag delivery means 2 rotates once, the bottom seed bag stored in the stock case 1 at the address in each of groups A, B, and D is moved by its contact resistance. The lower roll 31 and upper roll 32 of the seed bag pull-out means 3 are fed out to the point where they are caught between the seed bag pull-out means 3, and then the lower roll 31 and the upper roll 32 of the seed bag pull-out means 3 are moved to the left and right ears of the seed bag (in the case of a thin seed bag) or the body (in the case of a thick seed bag). ).

Therefore, there are 10 seed bags at address m in the lower row of group A.
2 seed bags with address n in the middle row and 5 seed bags with address o in the lower row of group B fall onto the first belt conveyor 4a on the right in the figure, and the seed bags with address n in the upper row of group D fall. Three seed bags at address q fall onto the first belt conveyor 4b on the left in the figure. thus,
When seed bags corresponding to one order slip selectively fall onto the first belt conveyors 4a and 4b, the first belt conveyors 4a and 4b are activated, respectively.
The seed bag passes through the chute 5a, 5b at the conveyance end and falls into the bucket 6a of the bucket conveyor 6, and then the first belt conveyor 4a, 4b stops.

Subsequently, the bucket conveyor 6 advances by a pitch corresponding to one bucket, and the bucket conveyor 6b moves forward by the pitch of one bucket.
Located under a. In this way, the seed bag feeding process is performed one after another for each order slip.

When the bucket 6a reaches the bottom of the printer 8, the corresponding documents such as delivery notes and invoices are printed and cut, the corresponding documents are dropped into the bucket 6a, and when they reach the end of the conveyor and fall over, they are stored in the bucket 6. The seed bags that had been placed are dropped onto the second belt conveyor 7. The second belt conveyor 7 then operates for a short time and transports the seed bags to the end of the conveyor. At the end of the second belt conveyor 7, the seed bags and delivery notes for each order are manually processed.
Documents such as invoices are collated and packed into bags.

<Effects of the Invention> As can be seen from the above description, the automatic seed bag feeding device of the present invention has a stock case row, stacks and stocks seed bags for each product, and supplies the required types according to customer orders. - Quantities are selectively taken out almost simultaneously from the stock cases at the required addresses and collected into one bucket.

Furthermore, by providing the first belt conveyor and chute between the stockcase row and the bucket conveyor provided below it, the structure allows many stockcase rows to be arranged in parallel or in multiple stages. , thousands or tens of thousands of types of seed bags can be stacked and stocked for each product.

In addition, the seed bag delivery means at a desired address is simultaneously and selectively driven, and the bottom seed bag stored in the stock case is slightly sent out by the seed bag delivery means, and then the seed bag delivery means is forcibly pulled out. Because it is,
Even if the order contents of individual order slips are diverse, and even if the types and quantities of seed bags are thousands or tens of thousands, it is possible to simultaneously selectively and reliably feed seed bags into one bucket. Can be integrated quickly.

In addition, the printer feeds documents such as delivery notes and invoices together with the accumulated seed bags to the bagging position, making it easier to compare delivery notes and invoices with products and bag them. I can do it well.

In the end, there will be no mistakes and less manpower will be required, resulting in a significant reduction in labor costs and mechanization, labor savings, and space savings.
