  However, in the conventional apparatus, the cardboard box B is moved by the transfer device 101 driven by a power source such as a motor, and the cardboard box B at this time uses a force that moves relative to the sealing portion 102. The sealing portion 102 is configured to affix the adhesive tape T to the cardboard box B. For this reason, the conventional apparatus requires an energy source such as a power source for operating the power source of the transport apparatus 101, and there is a problem that it is not suitable for use in a place where it is difficult to prepare the energy source such as Tabata. In addition, since the conventional apparatus is equipped with the conveying device 101, its power source, and the configuration for supplying the energy source of the power source, the weight of the machine becomes heavy, and in a relatively soft place on the ground such as a field. There is also a problem that it is difficult to move and install the machine.

In order to solve the above problems, the corrugated cardboard sticking machine of the first invention is:
A cardboard box in which a pair of left and right outer flaps are folded inward is capable of transporting a cardboard box in a certain direction parallel to the joint line of the left and right outer flaps, and a sealing portion disposed above the transport path. Equipped and
The cardboard box is a manual cardboard tape applicator configured to apply an adhesive tape along the joining line by using a force that the cardboard box moves relative to the sealing portion,
The sealing portion is configured such that parts other than the lower side portions thereof are supported by the body, so that a pair of spaces are formed in the vicinity of the both side portions,
When an operator pushes both hands into the pair of spaces while holding both upper corners of the cardboard box placed on the entrance side of the transport path in the vicinity of both upper corners on the rear side in the transport direction, the cardboard box Is pushed out to the outlet side of the conveyance path.

  The part where the sealing part is supported by the airframe is not particularly limited, but it is preferable that the part is near the front part or the upper part of the sealing part so that the space can be secured as wide as possible. Moreover, when making this supported site | part into the side part (except the said lower both sides) of the said sealing part, it is preferable to make it the site | part of the conveyance direction front side rather than the center part in the front-back direction of this sealing part. . Moreover, it is preferable that the lower both side parts of the sealing part do not have an unevenness that hinders both hands to be pushed in, and it is exemplified as a shape that smoothly extends in the front-rear direction (no catch).

  According to this configuration, since a pair of spaces are formed in the vicinity of both side portions in the lower portion of the sealing portion, an operator can manually move the cardboard box on the transport path using the spaces. Can be moved. Then, when an operator manually moves the cardboard box on the transport path, the sealing unit is configured to operate using the force of the cardboard box moving relative to the sealing unit at this time. In addition, since it does not include a configuration including a power source (motor, engine, etc.) as in the conventional transfer device, it can be made light in weight and does not require an energy source (electricity, fuel, etc.) for operating the power source. . For this reason, it can be used in places where it is difficult to prepare the energy source.

On the rear side in the transport direction of the sealing portion, a cover formed to protrude to the lower side of the sealing portion is provided in order to narrow the gap between the bottom portion of the sealing portion and the top surface of the cardboard box. An embodiment is illustrated.

  According to this configuration, it is possible to prevent an operator's hand pushing into the space from entering the gap.

As a corrugated cardboard sticking machine of the third invention, in the first invention,
At the rear side in the conveying direction of the sealing portion, the protruding length to the side of the protruding portions existing on both sides of the lower portion of the sealing portion protrudes to the side more than the longest one. The aspect in which the formed cover was provided is illustrated.

  According to this configuration, it is possible to prevent the operator's hand pushing into the space from colliding with the protrusions present on the lower side portions.

As the corrugated cardboard sticking machine of the fourth invention, in any one of the first to third inventions,
The airframe can be placed on the installation surface by a support leg that contacts the center of gravity of the cardboard tape applicator and a wheel that contacts the position away from the contact position of the support leg toward the exit of the conveyance path. The aspect comprised in is illustrated.

On the upper side of the base 13, the transport path 2 is supported via a parallel motion mechanism 16 so that the vertical height can be adjusted. This height adjustment is performed by a vertical handle 17 provided on the rear side of the base. One support column 10 on the rear side of the base 13 extends upward to the height of the sealing part 3. The other support column 11 on the rear side of the base 13 extends further to the upper side than the height of the sealing portion 3, and is bent inward in the width direction of the machine body 4 on the upper side. Both struts 10 and 11 are divided into upper and lower portions at the intermediate portion between the height position of the transport path 2 and the height position of the sealing portion 3, and the front and rear direction of the machine body 4 is at the upper and lower joint portions, respectively. An upper frame 26a and a lower frame 26b are attached to each other, and the upper and lower portions of the joint portion are detachably connected at both frames 26a and 26b. Thereby, the relative position in the horizontal direction above and below the joint portion can be adjusted. Both end portions of a substantially U-shaped frame 21 extending forward of the machine body are connected to height positions equivalent to the sealing portion 3 in both the columns 10 and 11. The portions of the both sides of the substantially U-shaped frame 21 that are closer to the front side of the machine body are respectively supported by the vertical frames 21a that are erected on the upper frames 26a. The substantially U-shaped frame 21 and the column 11 support the sealing portion 3 as will be described later. In this way, the main constituent elements of the tape applicator 1 are supported by the rear support columns 10 and 11. As a result, the support legs 14 provided on both the columns 10 and 11 are grounded so as to support the vicinity of the center of gravity of the tape applicator 1 of the present invention. As described above, the airframe 4 is configured to be stationary on the installation surface by the support legs 14 and the wheels 15.

  The conveyance path 2 includes a roller conveyor 24 for conveying the cardboard box B from the rear side to the front side of the machine body 4 and a guide portion 25 for guiding the direction of the cardboard box B on the roller conveyor 24. . The guide portion 25 includes a guide rod 28 supported via a parallel motion mechanism 27 on the inner side of each upper frame 26a. On the rear end side of each upper frame 26a, a handle 29 for lifting and moving the body 4 is provided. Both guide bars 28 are supported in parallel with each other, and guide the direction of the cardboard box B by sandwiching the side surface of the cardboard box B from both the left and right sides. The distance between both guide bars 28 can be adjusted by a parallel motion mechanism 27 according to the cardboard box B to be conveyed.

  The sealing portion 3 is formed so that the size in the width direction of the transport path 2 is smaller than the size of the cardboard box B to be sealed in the same direction, and the front end portion and the substantially central portion in the front-rear direction at the upper side portion, The front end of the substantially U-shaped frame 21 and the upper end of the support column 11 are supported respectively. As described above, the sealing portion 3 is configured such that both lower side portions thereof are not supported by the body 4 and portions other than the both side portions are supported by the body 4. The spaces S and S are formed. Then, as shown in FIG. 3, the operator holds both upper corners of the cardboard box B placed on the entrance side of the transport path 2 near the upper corners on the rear side in the transport direction with both hands H and H. When both hands H, H are pushed into the spaces S, S, the cardboard box B is pushed out to the exit side of the transport path 2.

  A cover 30 is provided on the rear side in the transport direction of the sealing unit 3. The cover 30 is formed in a shape projecting below the lower part of the sealing part 3 and on both the left and right sides. The downward projecting portion of the cover 30 narrows the gap between the bottom portion of the sealing portion 3 and the top surface of the cardboard box B. The lower edge of the cover 30 has a shape curved forward in the transport direction so as not to damage the top surface of the cardboard box B. Overhanging portions on both the left and right sides of the cover 30 are equal to or longer than the longest side protruding length among the protruding portions (end portions of the respective supporting shafts) existing on the lower side portions of the sealing portion 3. It is formed to project to the side.

  As shown in FIG. 4, the sealing unit 3 is configured so that the tape feeding body 31 that feeds the adhesive tape T and the top surface of the cardboard box B roll along the joining line L, and the tape feeding body 31 on the outer circumferential surface thereof. The pressure-sensitive adhesive tape T that is fed out is pressed so that the pressure-sensitive adhesive surface is in close contact with both the left and right outer flaps Fo, and the pressure-sensitive adhesive tape T that is fed from the tape feeding body 31 is cut into a predetermined length. And a pressing roller 33 that presses from above so that the left and right outer flaps Fo do not float when the pressing roller 33 rolls on the rear surface in the advancing direction of the cardboard box B.

  The tape supply body 31 supplies the adhesive tape T fed from the tape roll R to the front portion of the pressing roller 32 via the guide rollers 40 and 41 with the adhesive surface side facing forward. The front end of the adhesive tape T is sandwiched between the tape guide plate 42 and the tape pressing plate 43 at the immediately preceding portion. When using the adhesive tape T having a strong adhesive force, it is not allowed to pass through the guide roller 41 (see the tape T indicated by the two-dot chain line in FIG. 4). This is because the adhesive surface of the adhesive tape T is in contact with the outer peripheral surface of the guide roller 41. Therefore, in the case of the adhesive tape T having a strong adhesive force, the adhesive tape T strongly adheres to the outer peripheral surface of the guide roller 41 and presses. This is because the roller 32 is lifted, and the pressure-sensitive adhesive tape T is insufficiently pressed against the cardboard box B. In order to prevent this shortage of pressing, if the pressing roller 32 is strongly urged against the top surface of the cardboard box B while passing through the guide roller 41, the cardboard box B is manually conveyed. This causes a problem that the operation burden on the operator is increased and the cardboard box B is easily damaged.

  The two front and rear pressing rollers 32 and 33 are respectively attached to the lower ends of the arms 36 and 37 that are rotatable about the support shafts 36a and 37a, and the arms 36 and 37 are opposite to each other in conjunction with each other. Are connected by a connecting rod 38 so as to be pivoted to each other and biased by biasing means (not shown) in a direction in which the distance between both arms 36 and 37 is increased.

  The cutter 34 has a tip formed in a saw blade shape, and is positioned between the pressing rollers 32 and 33.

  The pressing roller 35 is provided such that the lower end of the peripheral surface is positioned at substantially the same height as the top surface of the cardboard box B.

  Next, the usage method of this tape applicator 1 is demonstrated, referring FIG. Here, it is assumed that an ordinary adhesive tape T is used instead of the adhesive tape T having a strong adhesive force. First, an operator stands on the rear side of the machine body, puts the cardboard box B on the entrance of the conveyance path 2, puts the cardboard box B into a state where the inner flaps Fi and Fi and the outer flaps Fo and Fo are folded inward, and the cardboard box. Holding both upper corners on the rear side in the conveyance direction of B with both hands, the cardboard box B is pushed toward the exit side of the conveyance path 2. At this time, since the cover 30 is provided on the sealing part 3, the operator's hands H, H are too close to both sides of the sealing part 3, or the bottom of the sealing part 3 and the top surface of the cardboard box B There is no intrusion. When this cardboard box B reaches a predetermined position, the upper part of the front surface of the cardboard box B comes into contact with the adhesive surface at the tip of the adhesive tape T that has been fed out from the tape roll R by a predetermined length (see FIG. 5A). The leading end of the adhesive tape T is pressed against the cardboard box B by the pressing roller 32 positioned on the front side in the transport direction. As the cardboard box B moves forward, the pressing roller 32 rolls upward on the front surface of the cardboard box B while pressing the adhesive tape T, and then the cardboard box B is moved along the joining line L of the left and right outer flaps Fo. The top surface is sealed by rolling the top surface. At this time, the pressure roller 33 is also raised to the height of the top surface in conjunction with the pressure roller 32 by the connecting rod 38, and the pressure roller 33 also seals the top surface following the pressure roller 32 ((b) in the figure). )reference). At this time, the cutter 34 floats from the top surface, but when the pressing roller 32 is removed from the top surface, the cutter 34 cuts the adhesive tape T at a predetermined length from the rear end of the top surface. (Refer to (c) in the figure). After that, the pressing roller 33 rolls down the rear surface following the top surface of the cardboard box B, and the adhesive tape T is pressure-bonded to the rear surface to the tip (see FIG. 4D). At this time, the left and right outer flaps Fo and Fo are pressed to the height of the top surface by the pressing roller 35, and the left and right outer flaps Fo and Fo are sealed without being lifted from the main body of the cardboard box B. Until this state is reached, when the operator pushes the cardboard box B toward the exit side of the transport path 2, the cardboard box B sealed on the exit side of the transport path 2 is sent out.

  According to the corrugated cardboard sticking machine 1 of the present example configured as described above, a pair of spaces S, S are formed in the vicinity of both side portions in the lower portion of the sealing portion 3, so that the space S , S can be used to manually move the cardboard box B on the transport path 2. Then, when the operator manually moves the cardboard box B on the transport path 2, the sealing unit 3 is operated by using the force that the cardboard box B moves relative to the sealing unit 3 at this time. Since it is configured and does not include a configuration including a power source (motor, engine, etc.) as in the conventional conveying device, it can be made lightweight, and an energy source (electricity, fuel, etc.) for operating the power source is provided. unnecessary. For this reason, it can be used in places where it is difficult to prepare the energy source.

  Since the cover 30 is formed so as to protrude below the sealing portion 3 in order to narrow the gap between the bottom of the sealing portion 3 and the top surface of the cardboard box B, the operator pushing into the spaces S and S Can be prevented from entering the gap between the bottom of the sealing part 3 and the top surface of the cardboard box B.

  Further, since the cover 30 is formed so as to protrude sideways more than the longest one of the protrusions present on both sides of the lower portion of the sealing portion 3, It is possible to prevent the operator's hands H, H pushed into the spaces S, S from colliding with the protrusions present on the lower side portions.

  The machine body 4 includes support legs 14 and 14 that are grounded so as to support the vicinity of the center of gravity of the corrugated cardboard sticking machine 1, and wheels that are grounded to a position away from the ground contact position of the support legs 14 and 14 toward the exit side of the conveyance path. 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15, 15. The machine 1 can be moved by the wheels 15 and 15.
