Description

  The present invention relates to a seed packing device for manufacturing a net bag containing seeds by joining openings of bag members cut from a long cylindrical net raw material wound around a roll, and in particular, a net raw material. The present invention relates to a seed packing device that improves the recovery rate of net scraps generated by cutting of a net.

Recently, for example, 60 ° C. has been used for disinfection of seed pods such as sterilization and sterilization of pathogens (rice blast disease, stupid seedling disease, seedling bacterial disease, etc.) adhering to the surface of seed pods and lurking between rice husks and pericarp Hot water disinfection is performed in which the soy sauce is soaked for about 10 minutes.
At that time, each farmer puts a certain amount of seed pods in a plurality of net bags and ties their mouths to execute the hot water disinfection. A net bag in which a predetermined amount (for example, 4 kg) of seed pods is automatically made by a packing device is made.

In the seed packing device, a long cylindrical net material wound around a roll is fed a predetermined amount, cut at a predetermined length from the opening at the front end in the feed direction, and a predetermined length at which the rear end also opens. The bag member is obtained. Therefore, the bag member cut out from one net raw material can be obtained by cutting the leading end and the trailing end of the feeding direction at the cutting position.
And in the cutting position, the opening part of a rear end is closed previously by heat welding. Then, the bag member closed only on one side is fed further, and seeds are put into the bag member from the opening at the tip in the feed direction, and then the tip opening is closed by heat welding, and thus the net into which the seed is put. A bag is obtained.

  By the way, the net raw material has a stitch size that prevents seeds from falling off, and fine net scraps are generated by cutting the cutter. Since the seed packing apparatus uses a cylinder as a drive source for each mechanism, if the net waste is scattered and caught in the rod portion of the cylinder, a malfunction of the cylinder is induced. Therefore, conventionally, in the seed packing device, a dust pan that receives net waste is disposed under the moving guide through which the bag member immediately after being cut passes, and the net that falls from the bag member when the cut bag member passes through the moving guide. Waste is collected (see, for example, Non-Patent Document 1).

Japan Vehicle Manufacturing Co., Ltd. website http://www.n-sharyo.co.jp/business/plant/seedcenter-flow.htm

However, the conventional seed packing apparatus has the following problems.
(1) In the conventional seed packing apparatus, since the moving guide is a flat plate, the net waste only falls on the dust pan from the edge of the moving guide. Therefore, most of the net waste generated by cutting has been sent to the next process while adhering to the moving bag member. And it will scatter by the movement of the bag member at the time of throwing seeds, etc., and as mentioned above, operation failure of a cylinder etc. will be caused.

(2) Moreover, in the conventional seed packing apparatus, while moving a bag member along a plate-shaped movement guide from a cutting position, the cut front-end | tip opening part will wind up outside by a contact resistance with a movement guide. Sometimes. Then, if a curl is attached to the opening at the tip, the next time the seed is put into the bag member from the opening, there is a problem that the chuck mechanism of the opening cannot properly grasp the tip opening. .

  Then, this invention is made | formed in order to solve the said subject, and it aims at providing the seed packing apparatus which is hard to curl the cut | disconnected bag member while improving the collection rate of a net waste.

  In order to solve the above problems, the seed packing device of the present invention is to manufacture a net bag containing seeds by joining the opening of a bag member cut from a net raw material wound around a roll, A seed packing device comprising: a moving guide that guides the bag member that contacts the cutting process from the cutting position; and a dust pan that is disposed below the moving guide and collects net scrap generated by cutting the bag member. The moving guide has a slit formed along a moving direction in which the bag member moves from the cutting position to the next process.

  In the seed packing device of the present invention, it is preferable that the slit is formed between a plurality of round bars arranged in parallel with a direction in which the bag member moves from the cutting position to the next process.

  In the seed packing device of the present invention, it is preferable that the surface of the movement guide that touches the bag member is small and is formed into a sine wave shape or a sawtooth wave shape along the moving direction of the bag member.

  In the seed packing device, when moving from the cutting position to the next process while being guided in a state where the bag member is in contact with the moving guide, the net waste generated by cutting the net raw material and adhering to the bag member is transferred to the moving guide. Since it falls into the dust pan through the slit and cannot be dragged to the bag member, the collection rate for collecting net scraps into the dust pan is improved. Further, by forming a slit in the moving guide along the moving direction in which the bag member moves from the cutting position to the next process, contact resistance generated between the bag member and the moving guide when moving from the cutting position to the next process. The bag member is less likely to roll up. Therefore, according to the said seed packing apparatus, while improving the collection | recovery rate of a net waste, it can make it difficult to curl the cut | disconnected bag member.

  In the seed packing device, the slit of the movement guide is formed between a plurality of round bars arranged in parallel with the direction in which the bag member moves from the cutting position to the next process, and the net scrap dropped on the round bar Slid on the surface of the round bar and dropped into the slit, so net scraps are less likely to remain on the moving guide. Therefore, according to the said seed packing apparatus, the quantity of the net waste scattered according to the movement to which a bag member moves to a next process from a movement guide can be reduced. Moreover, since the bag member moves in contact with the round bar in the seed packing device, the contact area where the bag member contacts the round bar is smaller than the contact area where the bag member contacts the plate-shaped movement guide. Therefore, it is possible to reduce the contact resistance generated between the movement guide and the bag member and to make it difficult to curl the cut bag member.

  In the seed packing device, since the surface of the moving guide that contacts the bag member has a sine wave shape or a saw-tooth wave shape, the bag member vibrates and shakes net scraps onto the dust pan when the bag member moves on the moving guide. be able to. Further, since the surface of the movement guide that contacts the bag member has a sine wave shape or a sawtooth wave shape along the movement direction of the bag member, the movement guide does not get caught when the bag member moves on the movement guide.

It is a schematic block diagram of the seed packing apparatus which concerns on embodiment of this invention. It is an external appearance perspective view of the movement guide shown in FIG. FIG. 2 is a schematic plan view around a movement guide shown in FIG. 1. It is the schematic block diagram which looked at the movement guide periphery shown in FIG. 1 from the side.

  Subsequently, an embodiment of the seed packing device according to the present invention will be described.

(Overall configuration of seed packing device)
FIG. 1 is a schematic configuration diagram of a seed packing device 50 according to an embodiment of the present invention. The arrows in the figure indicate the moving directions of the net raw material 51 and the bag member 61.
The seed packing device 50 manufactures a net bag 62 in which seeds such as seed pods are placed. The seed packing device 50 includes a net raw material 51, a first joint portion 52, a cutter 53, a slide mechanism 54, an end opening mechanism 55, a chuck mechanism 56, a seed input portion 57, and a second joint portion. 58, a belt conveyor 59, an automatic weighing unit 63, and a guarantee (name seal) printing unit 64. Between the cutter 53 and the seed throwing part 57, the moving guide 1 that characterizes the present embodiment is disposed, and a dust pan 60 for collecting net waste is disposed immediately below the moving guide 1.

  In the seed packing device 50, when the net raw material 51 having a long cylindrical shape wound around a roll is sent out to the seed input part 57 side through the first joint part 52 and the cutter 53, the slide mechanism 54 is sent out. The both ends of the net raw material 51 are held. The slide mechanism 54 is provided between the cutter 53 and the seed insertion portion 57 so as to be capable of linear reciprocation along the feeding direction of the net raw material 51 (see the arrow in the figure). The net raw material 51 is pulled out from between the cutters 53 by sliding toward the insertion portion 57 side. The bag member 61 is cut from the net raw material 51 with the drawn length, and the net bag 62 in the final form is formed by heat welding.

  At this time, first, the net raw material 51 drawn out for a predetermined length has a portion where the seal member and the guarantee slip (name sticker) supplied from the guarantee (name sticker) printing part 64 are pasted. Is then heat-welded and then sent further forward. When the heat welded portion of the net raw material 51 has passed the cutter 53, the cutter 53 cuts the net raw material 51. Thereby, the bag member 61 whose rear end side is closed is cut off from the net raw material 51. The bag member 61 is fed to the end opening mechanism 55 so as to slide on the movement guide 1 while being held by the slide mechanism 54, and the opening at the leading end of the feeding side is opened by the end opening mechanism 55. The opened tip opening is held by the chuck mechanism 56, and the bag member 61 is sent from the moving guide 1 to the lower side of the seed throwing portion 57. The bag member 61 is charged with a predetermined amount of seed (for example, 4 kg of seed meal) weighed by the automatic weighing unit 63 in the seed loading unit 57, and then the tip opening is thermally welded by the second joint 58. Thereby, the net bag 62 containing the seeds is completed. The completed net bag 62 is carried out by the belt conveyor 59.

(Configuration of travel guide)
Next, the configuration of the movement guide 1 will be described. FIG. 2 is an external perspective view of the movement guide 1 shown in FIG. The arrow in the figure indicates the direction in which the bag member 61 moves from the cutting position to the next process.
The movement guide 1 has a plurality of slits 5 formed in parallel along the feeding direction of the bag member 61 (see the arrow in the figure), and net scrap generated by cutting while the bag member 61 moves on the movement guide 1 is removed. It is configured to fall into the dust pan 60 through the slit 5.

  The width of the moving guide 1 is smaller than the width of the dust pan 60 (see FIG. 1), so that the dust pan 60 can reliably collect the net waste that has fallen from the moving guide 1. The movement guide 1 has a plurality of round bars 2 arranged in parallel, and both ends of each round bar 2 are fixed to the frame 3 by welding or the like. The round bars 2 are arranged at regular intervals to form a slit 5. The width of the slit 5 is such that the net scrap is dropped into the dust pan 60 through the slit 5 while maintaining the posture in which the bag member 61 is spread horizontally on the round bar 2.

  One end of the movement guide 1 is provided with a notch 4 for opening an end opening of the bag member 61 by bringing an end opening mechanism 55 (see FIGS. 3 and 4 described later) into contact with the bag member 61. ing. The movement guide 1 is provided with an inclination 7 so that the end on the side of the notch 4 is lowered. Fixing portions 8 having bolt holes 8a are erected at both ends of the moving guide 1.

(Moving guide)
FIG. 3 is a schematic plan view around the moving guide 1. FIG. 4 is a schematic configuration diagram of the periphery of the movement guide 1 as viewed from the side. The arrows in FIGS. 3 and 4 indicate the moving direction of the bag member 61.
The movement guide 1 has a plurality of round bars 2 in the feeding direction of the bag member 61 in order to reduce contact resistance generated between the bag member 61 and the movement guide 1 when the bag member 61 is moved in the arrow direction in the figure. It arrange | positions at the main body frame 65 of the seed packing apparatus 50 so that it may become parallel (refer arrow in the figure). At this time, the movement guide 1 is disposed at the end on the inclination 7 side on the side of the shooter 66 for guiding the bag member 61 below the seed throwing portion 57. And the movement guide 1 is attached to the seed packing apparatus 50 by inserting the volt | bolt 20 in the volt | bolt hole 8a, and fastening to the main body frame 65. FIG.

  In the movement guide 1 thus attached to the seed packing device 50, the slit 5 is provided above the dust pan 60 along the moving direction of the bag member 61 indicated by the arrow in the drawing. An end opening mechanism 55 is disposed between the notches 4 so that the end opening mechanism 55 can directly contact the bag member 61 moving on the movement guide 1 via the notches 4. Yes. Further, the movement guide 1 is provided with a chuck mechanism 56 above the slope 7, and the chuck mechanism 56 contacts the movement guide 1 when the bag member 61 is moved by grasping the opening at the front end of the bag member 61. It can be prevented.

(Function and effect)
In the seed packing device 50 having the above configuration, when the net member 51 drawn by the slide mechanism 54 for a predetermined length is cut by the cutter 53 to form the bag member 61, the slide mechanism 54 pulls the distal end side of the bag member 61. Thus, the tip opening portion is disposed between the end opening mechanisms 55. At this time, the bag member 61 slides on the movement guide 1 from the cutter 53 to the end opening mechanism 55 in a horizontal posture, and the tip opening is aligned with the chuck mechanism 56.

  In the seed packing device 50, when the cutter 53 cuts the net raw material 51 having stitches, net waste is generated, and the net waste adheres to the bag member 61. The net scrap adhering to the bag member 61 falls from the slit 5 to the dust pan 60 and is collected when the bag member 61 is pulled by the slide mechanism 54 and moves on the movement guide 1. More specifically, the net scrap adhering to the bag member 61 is a slit provided in parallel with the moving direction of the bag member 61 when the bag member 61 moves away from the bag member 61 when moving along the movement guide 1. 5 falls to the dust pan 60 as it is. Since the slit 5 is formed long over the entire length of the moving guide 1, the net waste can fall from the slit 5 to the dust pan 60 at any time along the moving guide 1 until it moves from the cutting position to the next process. it can. That is, even if the net waste does not move to both ends of the moving guide 1, it can fall to the dust pan 60 from an intermediate portion of the moving guide 1 through which the bag member 61 passes. For this reason, the net waste cannot be dragged to the inclination 7 of the movement guide 1 by the bag member 61. In addition, since the round bar 2 has a spherical cross section in a direction orthogonal to the moving direction of the net bag 61, the net scraps falling on the round bar 2 slide on the surface of the round bar 2 to form the slit 5 Easy to fall. Therefore, in the seed packing device 50 of the present embodiment, the net scrap generated by cutting the net raw material 51 easily falls to the dust pan 60 through the slit 5 of the movement guide 1, and the recovery rate for recovering the net scrap to the dust pan 60. Can be improved.

  Further, the movement guide 1 has a contact area with the bag member 61 that is smaller than that of the flat plate movement guide described in the prior art due to the slit 5. And the round bar 2 which comprises the slit 5 makes the cross section of the direction orthogonal to an axial direction spherical shape, and does not have a corner | angular part caught on the bag member 61 during movement. Therefore, in the seed packing apparatus 50 of this embodiment, the contact resistance that occurs when the cut bag member 61 moves along the movement guide 1 occurs when the bag member 61 moves along the flat plate movement guide. Since it becomes smaller than contact resistance, the front-end | tip opening part of the bag member 61 does not roll up outside by contact resistance, and it is hard to curl.

  The seed packing device 50 opens the tip opening of the bag member 61 aligned with the chuck mechanism 56 as described above by the end opening mechanism 55 and holds it by the chuck mechanism 56. Then, the bag member 61 is moved from the movement guide 1 to the seed input unit 57, and a predetermined amount of seed is input to the bag member 61. Since the bag member 61 drops the net waste from the slit 5 to the dust pan 60 when moving the movement guide 1, the bag member 61 is not sent to the next step with the net waste attached. Thereby, when the chuck mechanism 56 changes the posture of the bag member 61 and moves the bag member 61 from the movement guide 1 to the seed throwing portion 57, the net waste is scattered around and does not enter the rod portion of the cylinder, Cylinder malfunction due to net waste is less likely to occur. Further, when the chuck mechanism 56 holds the bag member 61, the tip opening portion of the bag member 61 is not wrinkled, so that the chuck mechanism 56 can properly grasp the tip opening portion of the bag member 61. Thereby, the seed packing apparatus 50 can arrange | position the bag member 61 correctly under the seed input part 57, and can inject | pour into the bag member 61 so that a seed may not be spilled. The seed packing device 50 heat-welds the front end opening of the bag member 61 into which the seeds are charged by the second joint 58, and carries the net bag 62 having both ends joined by the belt conveyor 59.

(Modification)
Needless to say, the seed packing device of the present invention is not limited to the above embodiment, and can be appropriately changed without departing from the spirit of the invention.
For example, in the above embodiment, the slit 5 is configured by arranging a plurality of round bars 2 in parallel and holding them with the frame 3, but as shown in FIG. You may form the slit 22 along the moving direction (refer the arrow in a figure).
Further, the surface of the moving guide 21 shown in FIG. 5 may be a sine wave shape 31 that undulates along the moving direction of the bag member 61 as shown in FIG. Further, for example, the surface of the moving guide 21 shown in FIG. 5 may be formed into a sawtooth wave shape 32 along the moving direction of the bag member 61 as shown in FIG. In this case, it is preferable to reduce the contact resistance with the bag member 61 by making the inclined surface 34 of the saw-tooth waveform 32 arc-shaped to eliminate the corners. Thus, by making the surface of the movement guide 21 into the sine wave shape 31 and the sawtooth wave shape 32, the bag member 61 vibrates when moving so as to slide on the movement guide 21, and is attached to the bag member 61. Waste can be shaken off from the bag member 61. Moreover, since the surface of the movement guide 21 is made into the sine wave shape 31 or the sawtooth wave shape 32 along the moving direction of the bag member 61, the bag member 61 does not catch on the surface of the movement guide 21 at the time of movement.
Further, for example, the movement guide 1 of the above embodiment includes a frame 3. On the other hand, as shown in FIG. 8, a moving guide 40 is provided by welding a plurality of round bars 41 to the leg portions 42 and the beams 43, and along the feeding direction of the bag member 61 (see the arrow in the figure). The slit 44 may be formed.
Further, for example, instead of the round bar 2, a bar having an elliptical cross section in a direction orthogonal to the axial direction may be used. In this case, it is desirable to arrange the elliptical bar so that the cross section is vertically long so that the net scraps can easily fall.
Moreover, the contact resistance which arises between the bag member 61 and a movement guide by changing into the round bar 2 and arranging a wheel along the conveyance direction of the bag member 61, and rotating those wheels in the moving direction of the bag member 61. May be made smaller.
For example, in the above embodiment, the round bars 2 are arranged at equal intervals, but the arrangement intervals of the round bars 2 may be changed.
For example, in the above embodiment, the slit 5 is provided in the entire movement guide 1, but the round bar 2 may be disposed so that the slit 5 is formed only on the movement path of the bag member 61.
For example, in the above-described embodiment, the seed packing device 50 that manufactures the net bag 62 for packing seeds has been described as an example. However, for example, the movement guide 1 is transferred to the seed packing device that manufactures the net bag in which only one is joined. May be applied.
For example, the seed packing device 50 according to the above-described embodiment is not limited to the net bag 62 containing seed pods, and may manufacture a net bag containing other seeds.
