Abstract

PURPOSE:To enable reliable feed of seed bags one by one, by a method wherein, by the use of an opening regulating plate in an orientation responding to a kind of the seed bag, only the lowermost seed bag is pulled out through a seed bag outlet irrespective of the thickness of the seed bag. CONSTITUTION:In case thick seed bags are piled up for containing, the drum part of a second seed bag F2 is forced into contact with the upper part of the outlet of the seed bag to stop it by means of an opening regulating plate 17 with which the seed bag is covered from outside. With this state, the drum part of the lowermost seed bag F1 is nipped by decreasing a gap width between a pair of a lower roll 31 and an upper roll 32 to pull it out. In case thin seed bags are piled up for containing, with the open regulating plate 17 turned upside down, both ends of the selvadge of the front side of the second seed bag F2 are forced into contact with suspending projecting parts 17a and 17b of the lower ends on both sides to stop the seed bag, and a gap width between the lower roll 31 and the upper roll 32 is increased, the selvadges on both sides of the lowermost seed bag F1 are nipped for pull-out.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a seed bag feeding method that can reliably feed seed bags one by one.

<Prior art> Seed bags approximately the size of postcards sold at type 1 flower shops and gardening shops;
In other words, there are about 30,000 bags filled with seeds of vegetables, flowers, etc. for each type, and since there are differences in the amount of seeds that are sealed, the number of seed bags can be several times larger. During the peak season, more than 1,000 varieties of seed bags are ordered, and there are many varieties where only one bag is ordered per day.

Traditionally, companies that supply these flower inserts to flower shops, seed stores, and gardening centers across the country have stocked thousands or tens of thousands of different types of flower inserts for each product on square-shaped shelves, requiring a large amount of manual labor. They prepare the necessary types and quantities of inserts from the sorted shelves to meet various customer orders, and then pack them and ship them. For this reason, the labor cost per person is enormous and a lot of space is required, making mechanization and automation a problem.

A problem encountered during its development was that the thickness of the inserts varied, making it difficult to ensure reliable supply of the negative side.

That is, the insert is generally small and rectangular as shown in FIGS. 2(a), (b) or 3(a), (b).

The insert F shown in Figures 2 (a) and (b) is made by stacking two sheets of insert paper, closing three sides, inserting the seeds, and then closing the other side. Generally, the seeds are small and the quantity is small, making it bulky. The closing part called the "ear" is not stable. Here, "unstable" refers to a state in which it is undulating in various ways depending on the type and product. The part to be accommodated is referred to as the "body section 1."

The insert F in Figures 3 (a) and (b) is made by folding a sheet of insert paper in the middle, closing the three sides, inserting the seeds, and then closing the other side. It is used when the bag is large and bulky, and the closing part called the selvage is all raised above the bottom of the bag and is not stable.

The inventor first stacked and stocked the inserts in a stock case, fed out the inserts one by one starting from the bottom, and then supplied the inserts by rotating a roller in contact with the lowest insert. I thought of a way to send it out by letting it go. However, we want to handle a wide variety of inserts in one stock case, and we also want to increase the stacking height, so the tightness of the inserts varies and the thickness of the inserts also varies. This caused a problem in which it was not possible to reliably supply the product.

The first problem is that the rollers can only feed the inserts halfway, and the second problem is that when inserts are stacked high, the bottom insert sticks closely to the second insert, causing uneven feeding. Therefore, either the delivery was not carried out, or the second and subsequent insertions were co-drawn.

<Object of the Invention> The present invention has been devised in view of the above-mentioned points, and the bottom insert can be smoothly separated from the second insert regardless of the type of inserts and the stacking height. It is possible to prevent the second and subsequent inserts from being pulled together, and to prevent the bottom insert from getting caught in the loading outlet of the stock case, thereby ensuring that the inserts are supplied one by one. This provides a bag feeding method.

<Structure of the Invention> The seed bag feeding method of the present invention involves stacking the seed bags in a stock case with the inserts slightly shifted and stacking the stocks so that the overlapping sides are inclined upward, and the rotary contact member is attached to the bottom wall of the stock case. Rotately contact the lowest insertion in the stock case through the notch, and the resistance causes the insertion to protrude as required from the loading outlet cut into the stock case peripheral wall. A pair of lower rolls and an upper roll are provided on the outside on the left and right sides, and the upper roll rides on the lower roll so as to rotate with it and can escape upward, and the lower roll and the upper roll are used to carry out the above-mentioned loading. This is a seed bag feeding method that pinches and draws out the inserts protruding from the outlet, and when stacking thick inserts, an opening adjusting plate that covers the upper part of the stacking outlet from the outside is used to close the second insert. When the bodies are brought into contact and stopped, the width of the pair of lower and upper rolls on the left and right is narrowed so that the bodies of the lowest inserts are sandwiched and pulled out, and thin inserts are stacked and accommodated. Take the opening adjustment plate upside down, and use the hanging protrusions at the lower ends of both sides to abut and stop both ends of the front ears of the second insertion, and widen the widths of the lower roll and upper roll. The feature is that the ears are inserted between the left and right sides of the bottom insertion and pulled out.

That is, first, by stacking the inserts in the stock case with the inserts shifted little by little and with the overlapping side facing upwards, the second and subsequent inserts that join the bottom insert can be stacked. Second, the rotating contact member is brought into rotational contact with the lowest insertion member in the stock case through a notch in the bottom wall of the stock case, and the resistance causes the insertion to be held in the stock case. A pair of left and right lower rolls are provided on the outside of the insertion outlet of the stock case, and a pair of left and right upper rolls are provided on the outside of the insertion outlet of the stock case, and a pair of left and right upper rolls are provided on the outside of the insertion outlet of the case, and a pair of left and right upper rolls are attached to the left and right upper rolls so as to rotate along with these rolls. By sandwiching and pulling out the inserts protruding from the insertion outlet with the roll, the inserts can be fed completely instead of halfway. Thirdly, thick inserts can be stacked and accommodated. In this case, the opening adjustment plate that covers the upper part of the insertion outlet from the outside is used to stop the body of the second insertion, and the width of the pair of lower rolls and upper rolls on the left and right is narrowed so that the width of the upper roll is narrowed. The body of the bottom insert can be inserted and pulled out, and if thin inserts are stacked, the opening adjusting plate can be installed upside down and the hanging protrusions at the lower ends on both sides can be used to pull out the second insert. By stopping both ends of the front ears in contact with each other, and widening the width of the lower and upper rolls to sandwich and pull out the ears on the left and right sides of the lowest insertion, even if the insertion is thick, Even if the seed bag is thin, the bottom insert of the seed bag can be pulled out from the insert outlet, and the second and subsequent inserts are not pulled out together.
This enables the supply of inserts to be reliably supplied one by one.

<Example> Hereinafter, examples of an automatic loading and feeding device using the seed bag feeding method of the present invention are shown in FIGS. 1, 4, 5, 6, 7, and 8. This will be explained with reference to FIG.

Figure 1 is an overall schematic diagram of the automatic loading and feeding device. There are four stock case groups in which group A, group B, and group 0 and D face each other. It consists of a three-stage stock case row in which many of
The inserts stocked in the stock cases l are supplied onto the first belt conveyor 4a or 4b, respectively, by the loading/unloading means 2 and the loading/unloading means 3 provided corresponding to each stock case l, It passes through shoes) 5a and 5b, falls into the bucket) 6a at the required upstream position of the packet conveyor 6, joins documents such as delivery notes and invoices that are printed and cut off by the printer 8 at position 6n, and then They are fed onto the second belt conveyor 7, and at the end of the second belt conveyor 7, the two insertions are manually compared with documents such as delivery notes and invoices, and then packed into bags.

To explain in detail below, Figure wIJ4 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, FIG. 6 shows that the stock case 1 has a second
The thin insert Fl shown in the figure.

F2. 7 shows a front view of the stock case 1, and FIG. 8 shows the thick inserts Fl, F2, F2, etc. shown in FIG.・・・
Fig. 9 shows a front view of the same as seen from the front.

As can be seen from Figures 6 and 8, stock case 1
is a rectangular horizontal cross section that is slightly larger than the insert, and has a front side wall 11, left and right side walls 12, 13, a rear side wall 14, and a bottom wall 15. The front wall 11 and the rear wall 13 are parallel to each other and tilted backward at an angle of about 15 degrees, and the type 1 bags Fl, F2. ... are stored so that they are stacked with slight deviations, and the load of the second and subsequent insertions that is applied to the bottom insertion is suppressed to a minimum. The adhesion force with the loading and unloading means 2 is made to be sufficiently smaller than the unloading force of the loading and unloading means 2. The stock case l has a seed bag outlet on the front wall 11, a cutout 18 on the bottom wall 15, and a wide slit 19 on the rear side v13 extending from the upper end to the lower end. For the exit of the type 0 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 is arranged so that the rubber body 22 of the inserting and feeding means 2 provided below feeds out the lowest seed bag F1 in the stock case. The slit 19 is wide enough from the top and bottom to ensure that the stock condition of the seed bag can be seen from the rear of the case, making it possible to modify the stock and check the remaining stock. .

At the upper ends of the side walls 11, 12.13, bent rails 111, 111 are fixed outwardly, respectively, and the front end of the bottom wall 15 is provided with a pair of mounting plates 112, 112 corresponding to each stock case 1 on which it is placed. When placed on the rear end and slid forward, the fitting rails 111, 111 fit into the pair of placement plates 112, 112 and come into contact with the stopper 113, so that the stock case l slides forward. 112.
112 so that it cannot be lifted up.

As can be seen from FIGS. 5 to 9, the insertion and delivery means 2 includes:
A first common rotation shaft 23 provided at the bottom of each stock case row, and three first common rotation shafts 23 provided for each stock case group at the upper, middle, and lower rows of each stock case group.
a motor 26 that rotates a motor 26; a clutch 24 provided corresponding to each stock case 1; It consists of a rotating disk 21 which is rotated by a rotary disk 21, a rubber body (loading and delivering tool) 22 which is stepped on one side of the circumference of the rotating circle m2X, and a positioning means 25 which positions the rotating disk 21 at a fixed position. The timing belts 27, 27 transmit the rotation of the output shaft 28a of the motor 2B to the three first common rotating shafts 23. The motor 26 is driven when it becomes necessary to feed seed bags from at least one stock case in the stock case group.

One or more clutches 24 that need to feed a seed bag are turned on at the same time, and a phototube switch 27 shown in FIGS. Once the number of bags is counted, it will turn off again. For this reason, the rubber body 22 provided with a convex step on 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 Fl, it is inserted into the insertion/drawing means 3 due to contact resistance. It is designed to send it out until it gets caught.

As can be seen from FIGS. 5 to 9, the insertion/drawing means 3 is as follows.
For each stock case 1, a pair of left and right upper rolls 32 are placed on a pair of left and right lower rolls 31. The lower roll 31 and the upper roll 32 are formed with a rubber layer on their outer peripheries in order to maintain a feeding friction force. The pair of upper rolls 32 are attached to a floating shaft 35 provided for each stock case so as to rotate together with the pair of lower rolls 31, and springs 38.3 pull both ends of the floating shaft 35 downward.
At 8, rolling pressure is applied to the lower roll 31 and the roll is allowed to escape upward. Every pair of lower rolls 3
1 is fixed at a freely adjustable interval to Miki's second common rotating shaft 33, which is provided corresponding to the stock case rows in the upper and lower rows of each stock case group, respectively. The common rotating shaft 33 is connected to the first common rotating shaft 23 of each corresponding stage via a timing belt 34, and is rotated using the motor 2B provided for each stock case group as a common drive source. It looks like this. Note that another motor may be provided, and 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 maintaining the horizontal position, and is guided by the above-mentioned spring 3.
It is pulled downward at 6.38. When the seed bag is sent out by the selectively operated inserting and delivering means 2, the inserting/drawing means 3 pulls out the seed bag by pinching it, and drops it onto the first belt conveyor 4a or 4b.

As shown in FIG. 6, the inserting/drawing means 3 includes the thin and rare Fl, F2. . . 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 rare left and right ears, and , the opening adjustment plate 17 of the stock case 1 has hanging stopper parts 17a and 17b at both corners of the lower end that escape the body of the second rare F2 from the bottom and come into contact with the front ends of the left and right ears, so that the second rare F2 I'm trying to keep it from appearing together with the first rare Fl. Moreover, as shown in FIG. 8, the loading/unloading means 3 is attached to the stock case l, as shown in FIG.
l, F2. . . , a pair of lower rolls 31 and an upper roll 32, respectively, as shown in FIG.
The spacing between the stock case 1 and the stock case 1 is adjusted to be small, and the opening adjusting plate 17 of the stock case 1 is used upside down, that is, when the stock case 1 is used upside down. / The bar parts 17a and 17b are attached so that they are on top, and both corners are cut and the lower end of the plate is smooth and suppresses the front end of the chest of the second rare F2 from the bottom so that it does not come out.

The first belt conveyors 4a and 4b are provided below between stock case groups A and B and between C and D, where the three stock case rows face each other. The number -
Belt conveyors 4a and 4b.

A shoe that operates for a certain period of time after the loading/unloading means 2 and loading/unloading means 3 of the corresponding stock case groups A and B or C and D stops operating, and transports rare items by a length slightly larger than the stock case row) 5a.

5b are provided at the conveying ends of the first belt conveyors 4a, 4b, respectively, and the lower ends of the chutes 5a, 5b correspond to the packets 6a at a required upstream position of the packet conveyor 6 installed below. After the first belt conveyors 4a and 4b stop operating, the packet conveyor 6 is operated step by step at a pitch of one packet. The second belt conveyor 7 is installed below the conveyance end of the packet conveyor 6 in a direction perpendicular thereto, and is operated for a certain period of time after the packet conveyor 6 stops operating, and conveys the rare items to the conveyor end. The printer 8 is located above the packet 6n at a required downstream position of the packet conveyor 6, and prints documents such as a delivery bill, separates the documents, and drops them into a bucket 6n.

Next, the action will be explained.

Now, it is assumed that each stock case 1 of each group is stocked with different rarities.

In this case, the rare items F are stacked and stocked in the stock case 1 in a state in which they are shifted little by little, with the overlapping sides being slanted upward.

Therefore, the load of the second and subsequent rare items applied to the bottom rare item can be kept small, and the adhesion force between the bottom rare item and the second rare item is sufficient compared to the feeding force of the type 1 bag delivery means. becomes smaller. In addition, in addition to the fact that scarcity becomes easier to slip out,
When the seed bag is sent out by the loading/unloading means 2, the rear end of the seed bag is slightly lifted and a feeding force is applied, whereas the loading tip has an acute angle between the bottom wall and the front wall. As a result, it will not be lifted, and there will be no chance of rare items getting stuck in the loading outlet and not being able to come out.

When stacking and storing thick rare items, the body of the second rare item F2 is brought into contact with and stopped by the opening adjustment plate 17 that covers the upper part of the loading outlet from the outside. The abutment stop is not sufficient at both ends of the ear.

In addition, when storing thin rare items in a stack, the opening adjustment plate 17 can be installed upside down and the hanging protrusions 17 at the lower ends on both sides can be used.
At steps a and 17b, both ends of the front ears of the second rare F2 are brought into contact and stopped. This is because while it is difficult to stop contact with the rare body, the four corners of the ears are relatively stable.

Then, the order details written on the order slips mailed from customers in each region, including the orderer's name and address, and the rare product number and quantity, are entered into the personal computer.

Then, in this device, the rarity of various product numbers and quantities written on the order slip is simultaneously and selectively displayed in stock case groups A and B.
. Documents such as delivery notes and invoices are dropped and transferred onto the second belt conveyor 7, where documents are manually checked to see if they are rare and then packed into bags.

For example, according to the order details on a personal computer, 10 bags of inserts stocked in stock case 1 at address m in the lower row of group A, and 10 bags of inserts stocked in stock case 1 at address n in the middle row of group A. 5 bags of inserts stocked in stock case 1 at address 0 in the lower row of group B, and 5 bags of inserts stocked in stock case L at address 9 in the upper row of group D. Enter each of the three bags.

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 2B of group A operates until the feeding of 10 bags is completed.
The group motor 28 is operated until the feeding of five bags is completed, and
Each group motor 2B rotates 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 the groups A, B, and D rotate, and all the lower rolls 31 of the groups A, B, and D rotate. Only the clutches 24 at each address are turned ON at the same time, so that selective rotation is performed to perform insertion and delivery.

That is, the insertion and delivery means 2 at the m-th address in the lower row of group A is 1.
0 rotation, 2 rotations of the nth address in the middle row, the O# in the lower row of group B
The loading/unloading means 2 on the R base rotates 5 times, and the 9th position on the upper stage of the D group
The address insertion and delivery means 2 rotates three times. In this way, when each rotation is completed, each of the selected clutches 24
returns to OFF.

As can be seen from the above, when two or more addresses are selected in the same group, the motor 2B of that group will rotate as required in accordance with the largest number of items to be fed.

Therefore, each time the rubber body 22 of the type 1 bag delivery means 2 rotates once, the lowest insertion stocked in the stock case 1 at the corresponding address of each of groups A, B, and D, due to its contact resistance, It is fed out to the point where it is caught between the insertion/drawing means 3,
Then, the lower roll 31 and the upper roll 32 of the inserting/drawing means 3 sandwich the left and right ears of the inserter (in the case of a thin inserter) or the cavity (in the case of a thicker inserter) and pull it out. In this way, in the case of thin insertion, a pair of upper and lower rolls 31 on the left and right
．． The reason why the left and right ears of the type 1 bag are not raised much higher than the lower surface of the insert, and the ears of the type 1 bag are not raised much higher than the lower surface of the insert, and the bottom of the insert is roll 3
1, the upper surface of the lower roll 31 is not far away from the upper surface of the lower roll 31.On the contrary, in the case of a thick insertion, the left and right ears of the insertion stand out from the lower surface of the insertion, and the ears are When passing through the lower roll 31, it is far away from the upper surface of the lower roll 31, so it is impossible to pinch the left and right ears of the insertion with the rolls 31 and 32 and pull it out.
1.32 is made considerably smaller than the width of the insert, and is pulled out by sandwiching the body.

Next, as described above, the insertion of the mth address in the lower row of group A is 10.
The bags, the two stacked bags at the nth address in the middle row, and the five loaded bags at the zeroth address in the lower row of group B fall onto the first belt conveyor 4a on the right in the figure, and the bags at the upper row of group D fall. The three bags loaded at address 9 fall onto the first belt conveyor 4b on the left in the figure.

In this way, when the inserts corresponding to one order slip are simultaneously and selectively dropped onto the first belt conveyors 4a and 4b, the
The belt conveyors 4a and 4b operate, and the first type bags fall onto the packet 6a of the packet conveyor 6 through the chutes 5a and 5b at the conveying ends, and then the first belt conveyors 4a and 4b stop.

Subsequently, the packet conveyor 6 moves forward by a pitch of 81 minutes, and the bucket sb is positioned below the chute 5a.In this way, the loading process is performed one after another for each order slip. .

When the packet 6a reaches the bottom of the printer 8, the corresponding documents such as delivery notes and invoices are printed and cut, and the documents corresponding to the packet 6a are dropped.When the packet 6a reaches the end of the conveyor and falls over, it is stored in the packet 6. The inserts that have been placed are dropped onto the second belt conveyor 7. The second belt conveyor 7 is then activated for a short time, transporting the inserts to the end of the conveyor. Then, at the end of the second belt conveyor 7, the insertion of the ordered units and documents such as delivery notes and invoices are checked manually and the items are packed into bags.

<Effects of the Invention> As can be seen from the above explanation, according to the loading and feeding method of the present invention, (1) the stacking height can be increased; This is due to the fact that the insertions are slightly shifted and overlapped, so that the load of the second and subsequent insertions that is applied to the bottom insertion can be kept small, and the adhesion between the bottom insertion and the second insertion is reduced. This is because the force is sufficiently small compared to the feeding force of the insertion/feeding means.

■ Regardless of the stacking height, the bottom insert will never get stuck in the insert outlet and will not come out.If you adjust the seed bag outlet and the insert thickness appropriately, the insert can be easily removed. The lowest insertion slot from the loading port slides out without getting stuck at all. This is an insertion outlet in which a roll or other rotating contact member is brought into rotational contact with the lowest insertion in the stock case through a notch in the bottom wall of the stock case, and the insertion is cut into the peripheral wall of the stock case by the resistance. Then, a pair of left and right lower rolls provided outside the insertion outlet of the stock case and a pair of left and right upper rolls that rotate with these and can escape upward are used to protrude from the insertion outlet. This is because the insertion device is inserted and pulled out.

In addition to making it easier to slide out by slanting the loading outlet so that it is lower, the rear end of each bag is slightly lifted to apply feeding force when being fed out. This is because the tip of the bag is not lifted up because the corner between the bottom wall and the front wall is an acute angle.

■ The upper roll escapes upward according to the thickness of the insert, and there is no need to adjust the escape of the upper roll, thereby accommodating inserts with a wide variety of upper roll thicknesses and a wide variety of uses. It can be commonly used for all stock cases, and the structure of the loading/unloading means is solid, ensuring reliable operation, and is very effective in maintenance.

■ When storing thick insertions in a stack, the body of the second insertion is stopped in contact with the opening adjustment plate that covers the upper part of the insertion outlet from the outside, and also when thin insertions are stored in a stack. In this case, the aperture adjustment plate was installed upside down so that the hanging protrusions at the lower ends of both sides of the plate abutted and stopped both ends of the comparatively stable ears on the front side of the second insertion. Regardless of whether the bag is thick or thin, the bottom seed bag can be pulled out from the seed bag exit, and the second and subsequent seed bags can be pulled out together, making it possible to supply seed bags one by one. This will ensure reliable supply.

■ When viewed comprehensively from the above points, regardless of the type of insertion and the stacking height, the bottom insertion will smoothly separate from the second insertion, and the second and subsequent insertions will move forward. It can be prevented from being co-pulled, and the force of the lowest seed bag can prevent it from getting caught in the insertion outlet of the stock case, thereby making it possible to reliably supply each seed bag one by one.
