DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a semi-automatic box making apparatus. More specifically, the present invention relates to a novel semi-automatic box making device that automatically performs gluing, manually performs folding and pasting, and automatically performs crimping of a pasted portion.

[0002]

2. Description of the Related Art A conventional box making method will be described for a case of a box having a typical structure. In order to cut the mount into a predetermined shape as illustrated in FIG. 12 and to make the box P illustrated in FIG. 13 from the blank BL formed by forming the fold line f L , a manual method is used as a first method. There is. That is, FIG.
Is manually folded along the folding line f L , and each of the fixing portions t is raised from the bottom wall bw, and is adjacent to each other, that is, the front portion fw, the back portion rw, the left and right side portions rsw, This is a method of superimposing with lsw and sequentially binding using a wire stitcher in the overlapping portion. This method has the advantage that the equipment cost is low because a wire stitcher is used, and the box can be manufactured at low cost because it is performed only by a simple manual operation, but the production efficiency is low and a large number of boxes are required in a short time. This is inconvenient in some cases. Further, the completed box P occupies a certain space, so that the transportation efficiency is poor, the shape collapse due to the loading load is likely to occur during the transportation, and the wire is made of metal and the tip is sharp, so during the production of the box, Workers may be injured during the distribution process or when packing products.

A second method is to glue each fixing portion t of the blank shown in FIG. 12 by a gluing machine, set the blank at a predetermined position of a female die of a press machine, and press a male die from above. At the same time, the front wall fw, the rear wall rw, and the left and right side walls rsw and lsw in FIG. 12 are raised, and at the same time, both ends of each wall and the fixing part t are bonded with the glue. Is a method of crimping. This method has the advantage of good production efficiency because the gluing to the blank is performed automatically by a gluing machine, and the assembly (folding) of the box and the bonding of the glued portion are performed automatically by a press machine. Therefore, it is not suitable for small-lot production, and as in the case of the first method, the completed box P occupies a certain space, so that the transportation efficiency is poor and the shape is easily lost during transportation. In addition, since the mold needs to be replaced or adjusted each time the size of the box is different, there is a problem that both the equipment cost and the operating cost are high in the production of various small-quantity products.

[0004] A third method is to use a fully automatic box making machine that automatically and consistently performs all processes of gluing, folding, and pressing of a blank. This method is suitable for high-speed mass production and not for small lot production. Further, there is a problem that not only is the price of the box-making machine enormous, but also because the length of the box-making machine is as large as ten and several meters, so that it cannot be adopted easily.

[0005]

SUMMARY OF THE INVENTION The present inventor has found that the above-mentioned problems in the conventional method, namely, suitable for small-quantity production, and for equipment cost, transportation efficiency, shape loss during transportation, and injuries to box handlers. As a result of intensive research on various box making equipment to solve the problem of possibility, gluing to the blank is performed by a gluing machine, folding along the folding line is performed manually, and crimping of the glued part is performed by a press machine It was found that a semi-automatic box-making apparatus performed by the company was ideal. This box-making apparatus is suitable for small-lot production because it does not require a separate mold or replacement of parts, even if the type of box is different, and requires only slight adjustment. In addition, the box made by this box making device can be transported in a flat state, so that the transportation efficiency is greatly improved, and furthermore, the shape is prevented from being lost during transportation, and the box operator is injured. No fear.

However, the blank coming out of the gluing machine is folded along both the left and right hands along the folding line, and at the same time, the gluing portion is pressed and stuck at least two places in front and rear due to the structure of the box. There are various places such as front and back and left and right each two places, more than five places, etc.When folding the box with both hands, the part that has been folded and pasted first is later folded and pasted Then, the blank stands up and peels off due to the restoring force of the material elasticity. For this reason, it has not been possible to manually fold and affix the box blanks conventionally, so as described above, even if the method using a wire stitcher or the profitability in the case of large-scale small-quantity production is not possible. , A gluing machine and a pressing machine, or a fully automatic machine.

The inventor of the present invention has succeeded in solving the problem of peeling due to the restoring force of the material elasticity of the blank when manually folding and affixing the blank, thereby adopting the semi-automatic box making apparatus. It is made possible. Therefore,
The present invention provides a semi-automatic box making apparatus suitable for small-lot production, capable of reducing equipment costs and manufacturing costs, improving transport efficiency, and eliminating the possibility of shape collapse during transport and the possibility of injury to box operators. The first purpose. In addition, the second purpose is to prevent blanks glued by the gluing machine from being peeled off at the part where folding and pasting work has been completed first.
An object of the present invention is to provide a folding workbench for a box-making apparatus, which can efficiently perform folding and pasting work of other parts.

[0008]

In order to achieve the first object, a semi-automatic box making apparatus according to the present invention comprises an automatic gluing machine, a folding work table, and a press conveyor. The folding work table and the press conveyor are arranged in an L-shape or an inverted L-shape, and the automatic gluing machine is configured to set a feeding unit that feeds blanks one by one and a gluing position of the blank fed from the feeding unit. A conveying unit that conveys the sheet to a standby position, a gluing unit that glues the blank conveyed by the conveying unit to a predetermined position, and the sheet feeding unit and the conveying unit based on a detection state of a detector provided at the standby position. A control unit for controlling the driving and stopping of the unit,
The folding workbench, folding of the blank, which has a working surface of the rectangular for performing joining operations, at least one side excluding the automatic sizing machine sides and the press conveyor-side edge of the work surface, the work A certain distance between the surface
Forming a gap between the blanks, the work surface has a pressing member that holds the folded state by inserting the folded and pasted portion of the blank, and the press conveyor is folded at the work table. It is characterized in that the folded and pasted blank is sandwiched and conveyed, and the glued portion is pressure-bonded during the conveyance.

In the above configuration, when there is no blank at the standby position, the control unit drives the paper feeding unit and the conveying unit, and the paper feeding unit feeds out one blank. The transport unit transports the fed blank to a standby position. The automatic gluing machine glues a predetermined position of a blank fed and conveyed from a paper feeding unit. When the blank is transported to the standby position, the transport unit stops. When a blank is taken out from the standby position, the control unit causes the sheet feeding unit to feed out the next blank. The blank that has been glued and arrived at the standby position is taken out on the work surface of the folding work table by the operator, folded along the folding line using both hands, and attached. When the folded / pasted portion is inserted into the gap between the work surface and the holding member, standing / peeling of the folded / pasted portion is prevented.
The blanks, which have been folded and pasted at all other locations, are fed into the press conveyor from the work surface, and the glued portions are crimped during transportation.

A folding workbench for a box-making apparatus which achieves the second object of the present invention has a rectangular work surface on an upper surface,
At least one side of the work surface, one between its working surface
It is characterized in that it has a pressing member for forming a gap at regular intervals and slidingly inserting a portion of the blank folded and pasted with glue on the work surface to hold the folded state. Thus, each time the folding / pasting operation of one side of the blank is completed on the work surface, the folded / pasted portion is inserted into the gap between the work surface and the pressing member, and the blank of the folded / pasted portion is pressed by the pressing member. In a state in which standing and peeling due to material elasticity are prevented, folding and pasting work on other sides can be performed.

The holding member is preferably provided on one side of the work surface and on the side adjacent to the right or left side of the one side. In this case, when the front and rear sides and the left and right sides of the blank are folded and pasted, it is possible to prevent standing and peeling of the portions that have been folded and pasted first.

It is desirable that the holding member be adjustable in height from the work surface. Thus, the same workbench can be used for folding various blanks by adjusting the height of the pressing member according to the material thickness of the blank or the thickness after folding.

The paper feeding section A1 includes pulleys 2 and 3 rotatably suspended between the frames at two places before and after the frame 1.
, A plurality of paper feed belts 4 stretched over these pulleys 2 and 3, a motor M (FIG. 7), and an electromagnetic motor for transmitting or blocking the rotational force of the motor to one of the pulleys 2 and 3. And a clutch CL (FIG. 7). And
In the sheet feeding section A1, the frames 1 are arranged on both the left and right sides with an interval substantially equal to the width of the blank, and extend near the front end pulley 2 in parallel with the longitudinal direction of the sheet feeding belt 4,
Further, a side guide member 5 that rises at a required height from near the upper surface of the paper feed belt 4, a part of the paper feed belt 4 existing between the side guide members, and a side guide member 5
And a weir plate 6 provided so as to extend between the vicinity of the front end of the stacker. Thus, a plurality of blanks BL can be deposited on the upper surface of the sheet feeding belt 4 between the side guide members 5 on the stacker of the sheet feeding section A1.

As shown in FIG. 5, a gap is formed between the knife throat at the lower end of the weir plate 6 and the upper surface of the paper feed belt 4 so as to be slightly larger than the thickness of one blank.
By the rotation of the paper feed belt 4, only one blank at the lowermost end is fed out from the paper feed unit A1 toward the transport unit A2.

The transport section A2 includes front and rear pulleys 7 and 8 rotatably suspended between the frames 1, a plurality of transport belts 9 stretched around these pulleys, and the rotational force of the motor M. And a known transmission member for transmitting to one of the pulleys 7 and 8. By making the diameter of the transmission pulley 8a coupled to the pulley 8 of the transport section slightly smaller than the diameter of the transmission pulley 2a coupled to the pulley 2 of the transport section, the transport section has a lower speed than the transport speed of the transport section. Has been increased.

FIG. 7 shows the configuration of a control system for controlling the paper feed unit A1 and the transport unit A2. The control unit CON1 includes, as an example, a start switch SW mounted on the front side of the worktable B and a sheet feed belt 4 and a conveyor belt 9 for starting the automatic gluing machine. A first sensor S1 for detecting the presence / absence of a blank and a third sensor S3 for detecting the presence / absence of a blank, which is provided at a standby position of a gluing section A3 described later, are electrically connected to each other. The control unit CON1 starts the motor M when the start switch SW is turned on by the operator. Thereby, the transport belt 9 of the transport unit is constantly rotated. When the start switch SW is turned on, the first
When the sensor S1 and the third sensor S3 do not detect a blank, that is, when they are OFF, the electromagnetic clutch CL is turned on, so that the sheet feeding belt 4 is also rotated. Therefore, one blank is fed from the stacker. As shown in FIG. 5, the leading end of the blank is
N, the control unit CON1 turns the electromagnetic clutch CL off.
F to stop at the position where the leading end of the blank turns on the first sensor S1. In this state, the semi-automatic box making apparatus waits for an operation of starting a box making operation by an operator.
When the start switch SW is turned on again, the third
Since the sensor S3 is OFF (no blank), the control unit CON1 turns on the electromagnetic clutch CL to transfer the blank that has been fed to the position where the first sensor S1 of the sheet feeding unit A1 is turned on to the transport unit A2. Extend in the direction.

Above the upstream portion of the central conveyor belt 9, a pressing member 10 is provided to press against the conveying belt by its own weight, and a steel ball 11 rotatably disposed on the pressing member is provided. The steel balls are also rotated with the rotation of the conveyor belt 9 in contact with the conveyor belt 9.
Therefore, the blank whose leading end has been sent to the transport section A2 is
The sheet is sandwiched between the conveyor belt 9 and the steel ball 11, taken into the conveyor section, and conveyed.

When the first blank is fed from the paper feeding section A1 and its rear end is separated from the weir plate 6, the second blank is also replaced with the first blank due to friction between the upper and lower blanks in contact. It is fed out while sliding from. But,
Since the transport speed of the transport unit A2 is faster than the feed speed of the paper feed unit A1, the leading end of the second blank is first sensor S1.
Before reaching the position where is turned on, the rear end of the first blank is separated from the front end of the second blank by a forward distance.
Accordingly, the first sensor S1 is turned off when passing the rear end of the first blank, and is turned on again by the front end of the second blank.
Is turned on, the electromagnetic clutch CL is turned off, and the sheet feeding belt 4 is stopped.

Next, when the electromagnetic clutch CL is turned on,
The first blank is fed out after the first blank reaches the standby position and the third sensor S3 is turned on. Then, the blank is taken out from the standby position and the third sensor S3 is taken out.
Is turned off. Thereafter, every time the blank at the standby position is taken out, the next blank is fed from the sheet feeding section A1 to the transport section A.
It is to be fed to 2.

As shown in FIG. 6, a gluing portion A3 provided in the middle of the transporting portion A2 suspends and fixes the guide member 12 between the frames 1 at an intermediate position in the longitudinal direction of the transporting belt 9. The head of the bolt 13a is slidably inserted into a guide groove 12a formed over the entire length of the guide member 12, and the bolt is passed through the support member 14,
The nut 13b is screwed into the bolt protruding upward,
A required number of nozzles 16 with a built-in electromagnetic valve for spraying glue are provided on the supporting member 14 via a height adjusting member 15, and in the illustrated example, two nozzles 16 are provided.
A compressor (shown in the drawing) which supports the guide member 12 at a distance in the longitudinal direction, connects one end of a glue feed pipe 17 to the nozzle 16 and constantly applies a constant pressure to the glue sucked from a glue tank (not shown) at the other end. ) Is connected to the discharge port. The valve built in the nozzle 16 is opened and closed by energizing or stopping energizing a solenoid SOL attached to the support member 14. Each nozzle 16
Is attached such that the adhesive is sprayed toward the upper surface of the blank conveyed to the conveyor belt 9. In FIG. 6, reference numeral 18 denotes a guide member attached between the tip of the nozzle 16 and the conveyor belt 9 so that the blank can smoothly enter. The position of each nozzle 16 with respect to the blank can be arbitrarily adjusted according to the gluing position of the blank by loosening the nut 13b, moving the support member 14 in the longitudinal direction of the guide member 12, and tightening the nut 13b again. .

A second sensor S2 for detecting the arrival of the leading end of the blank is provided slightly upstream of the leading end position of the nozzle 16.

The gluing section A2 is provided with gluing control means for controlling gluing using a detection signal from the second sensor S2. As shown in FIG. 8, the glue control means controls the control unit CON2 to start the timer TM based on the detection signal when the second sensor S2 detects the leading end of the blank, and to energize the solenoid SOL at a predetermined timing. ,
By opening the valve of the nozzle 16 and spraying glue on the first predetermined position of the blank, the energization of the solenoid SOL is stopped, the solenoid SOL is energized again at a predetermined timing by the operation of the timer TM, and the valve is opened. Glue is sprayed on a predetermined position next to the blank. Glue spray timing, that is, solenoid SOL ON, O
The setting of the timer TM for FF can be easily changed in accordance with the position where the blank is glued, by exchanging a dial connected to the control unit CON2 or a program stored in the ROM. The distance between the support member 12 and the front end pulley 7 is slightly larger than the maximum length of the blank BL, and the portion between the support member 12 and the front end pulley 7 removes the glued blank from the next step. Is a standby position for waiting on the work table B for performing the folding operation until the worker takes out the work table B.

In the conveying section A2, the blank BL is also moved in parallel with the conveying belt 9 from the vicinity of the pulley 8 to the standby position.
Guide member 19 extending at intervals equal to the width of
Is provided. The side guide members 5 and 19 are mounted by the frame 1 and a mounting plate (not shown) so that the distance between them can be changed according to the width of the blank.

Then, slightly downstream of the front end pulley 7,
The previously described third sensor S3 for detecting the arrival of the leading edge of the blank and the removal of the blank is provided.

The work table B is provided with a transfer section A2 of the automatic gluing machine A.
Has a rectangular work surface 20 at a height slightly lower than the conveyor belt 9 at the standby position, and at least one side of the work surface, in a preferred embodiment, two adjacent sides, Press member 22 which forms a gap 21 into which the folded side of the blank can be inserted on the work surface
a, 22b are attached. Holding members 22a, 22
b may be constituted by a plate or a circular rod, or may have a structure in which a cylinder is rotatably supported by a shaft penetrating a hollow portion thereof.

In any case, the holding members 22a, 22b
The operator takes out the blank BL glued and stopped at the standby position in the automatic gluing machine A on the upper surface of the work table, folds the blank along a folding line in a predetermined order, and removes the glued portion. In the pasted state, the folded side portion is slid on the work surface and pushed into the gap 21 between the work surface 20 and the holding member 22a, and the folded portion restores the material elasticity of the blank. It is held up by force to prevent the glued portion from peeling off.

FIGS. 9 and 10 show a further preferred embodiment of the workbench. FIG. 9 is a sectional view, and FIG. 10 is a front view. In this embodiment, the holding member 22 is formed in an inverted L-shape.
Left and right 2 of fixed part 222 hanging down from horizontal holding part 221
A vertically long hole 223 is formed at the location, and the bolt 23 is inserted into the vertically long hole.
, And screwed into the front end surface of the top plate of the worktable, so that the height of the holding member 22 from the work surface can be arbitrarily adjusted. The structure for mounting the holding member so that the height can be adjusted is not limited to the above example. Various structures can be obtained by using a known technique.

The press conveyer C feeds the folded and glued portion by feeding the blank, which has been folded on the work table B, while maintaining the folded state. This is for completely bonding the glued portion by pressing while pressing.
The press conveyor C is rotatable between the front and rear frames 24 and between the front and rear frames 24, similarly at the left and right ends between the front and rear frames 24. Pressure belts 29, 30 for urging the lower belt 28, which is stretched over a lower pulley 27 suspended between the upper belt and the lower belt, so as to abut against each other.
And a motor (not shown) for applying a rotational force to one of the upper and lower pulleys. The front end of the lower belt 28 is extended to the work table B side from the upper belt 26, and the blank B taken out from the work surface 20 is removed.
The loading and feeding of L to the press conveyor C can be easily and reliably performed. The press conveyor C is constantly rotating. Behind the terminal portion of the press conveyor, a storage box for storing flat blanks (boxes) discharged from the conveyor is placed or a transport container or the like is placed.

Next, the operation of the embodiment device having the above configuration will be described. Stacker (4, 5,
In 6), it is assumed that a blank BL as shown in FIG. 11A is loaded as an example. In the figure, the dashed line indicates a broken line. The same reference numerals are used for the same parts as those in FIG. When the start switch SW is turned on, the control unit CON1 of the automatic gluing machine first activates the motor to rotate the conveyor belt 9. Next, the third sensor S3
When it is confirmed that the sensor S3 is not turned on, the electromagnetic clutch CL is turned on to rotate the paper feed belt 4. Accordingly, one blank at the bottom of the stacker is fed out. In FIG. 11A, the blank is moved in the direction of the thick arrow.

When the first sensor S1 is turned on by the leading end of the first blank that has been fed out, the control unit CON1 operates as follows.
The electromagnetic clutch is turned off to stop the feed belt 4. When the start switch SW is turned on again, the electromagnetic clutch CL is turned on, and the blank whose leading end has been stopped at the position where the first sensor S1 is turned on is sent out toward the transport section A2. Based on the transport speed of the transport unit being higher than the feed speed of the paper feed unit, the rear end of the first blank is separated from the front ends of the two blanks, and the first sensor S1 is turned off.
At the same time, since the leading end of the second blank turns on the first sensor S1 again, the control unit CON1 turns off the electromagnetic clutch CL.

The blank transported by the transport unit A2 is
In the gluing section A3, in order to turn on the second sensor S2, the control section CON2 of the gluing control means activates the timer TM and, based on the output of the timer, activates the valve of the nozzle 12 at a predetermined timing via the solenoid SOL. Open,
By closing, the glue GL is applied to a predetermined position of the blank as shown in FIG. In the case of the blank BL shown in FIG. 11, gluing is performed at two places before and after. The blank that has passed through the gluing process
When the controller 2 reaches the standby position by the continuous operation, the control unit CON1 stops the rotation of the motor M and stops the blank at the standby position to turn on the third sensor S3.

The folding operator OP stands on the opposite side of the automatic gluing machine A with respect to the work table B and takes out the blank held at the standby position of the automatic glue machine onto the work surface 20 of the work table B. By removing the blank from the standby position, the third sensor S3 is turned off again.
ON1 restarts the motor M, turns on the electromagnetic clutch CL, and sends the next blank that has been fed out to the first sensor S1 to the transport section A2.

The worker who has taken out the blank from the standby position first folds the two fixed portions t on the left and right sides (front side) of the blank with both hands (see FIG. 11 (c)). Further, after the front wall fw is folded and pasted with the glue GL (see (d)), the front wall fw is slid along the work surface 20 toward the pressing member 22 in the folded state,
It is pushed into the gap 21 between the work surface 20 and the holding member 22 (see (e)), and the folded state is maintained. Next, two fixed portions t on the left and right on the back side of the blank BL.
Is folded using both hands (see (f)), and then the back wall rw is folded and pasted with glue GL (see (g)).

Depending on the folding / adhering operation on the work table, the bonding between the fixing portion t and the front wall fw or the bonding between the other fixing portion t and the rear wall rw is not complete, so to say, in a temporarily fixed state. is there. In the case of the blank BL illustrated in FIG. 11, the folding operation is completed only by folding and pasting the front and rear two places in this way, so that the part pressed by the blank pressing member 22 is pulled out. ,Promptly,
Pressing the blank into the next press process, Press Conveyor C
It is put on the front upper surface of the lower belt 28 and fed (see the thick arrow in (h)).

In the press conveyer C, the folded and temporarily fixed blanks on the work table are nipped by the upper and lower conveyor belts 26 and 28, and the glued portions are completely pressed and then discharged from the rear end. You.

The discharged blank is finished into a flat box by the completion of the crimping of the folded and glued portions.
Therefore, when the boxes are transported to the destination of use, the total amount of dead space is very small, so that the transport efficiency is good. In addition, when the object is accommodated in this box, that is, when used as a box, the front and rear walls fw and rw and the left and right walls l
sw, rsw to cause the conventional box E shown in FIG.
Similarly to the above, it is used after being transformed into a box having an accommodation space. Therefore, a tool such as a conventional wire stitcher is not required, and there is no risk of injury due to the wire.

In the above embodiment, the folding / pasting operation was performed only at each of the two locations before and after the blank. However, depending on the shape of the blank, ie, the box, in addition to the two locations at the front and rear, two at each location at the left and right. In some cases, folding and pasting operations may be required. In this case, when the holding members 22a and 22b are provided on the side of the work table B on the side opposite to the automatic gluing machine A and the side on the side opposite to the press conveyor C, respectively, the folding / pasting operation of the front and rear two places is performed. Using the pressing members 22a on the side opposite to the automatic gluing machine A, the remaining two folding / pasting operations on the left and right sides are performed using the pressing members 22b on the side opposite to the press conveyor C. By doing so, not only the work can be performed quickly, but also the standing and peeling due to the restoring force of the material elasticity of the portion where the folding and pasting work has been completed can be prevented well.

In the illustrated example, assuming that the worker is right-handed, the blank that has been folded and pasted on the work table is moved to the press conveyor C installed on the left side of the worker. Therefore, the holding member of the work table is attached to the right side of the work surface. In the case of left-handed use, the press conveyor C is installed on the right side of the worktable, and the pressing member 22b is attached to the left side of the work surface.

According to the above embodiment, the start switch is set to the O
When N, the first blank is unwound from the stacker, is conveyed by the conveying unit, and reaches a predetermined position. Then, the gluing unit sprays the predetermined position of the blank, and is held at the standby position. Then, when the reserved blank is taken out by the operator, the next blank is automatically fed out, similarly glued, and is waited at the waiting position. Therefore, the feeding and gluing of the blank are performed automatically, and no manual operation is required.

At the work table, the operator takes out the blank from the standby position of the automatic gluing machine, and folds and pastes the two places on the front side and two places on the back side sequentially with both hands. Insert the previously folded / pasted part into the gap between the work surface and the holding member so that it can be held down. It is now possible to perform folding and pasting work using a press machine with female and male molds or a fully automatic box making machine. Blanks of any size can be accommodated without switching members. In addition, since folding and pasting operations can be performed efficiently, it is suitable for small lot production. Moreover,
Immediately after folding and pasting by hand, the glued portion is pressure-bonded by a press conveyor, so that peeling does not occur in the completed box.

Further, in the above-described embodiment, a common motor is used for the paper feeding unit and the transporting unit, and the components are used by the electromagnetic clutch. However, it is needless to say that different motors can be used for each unit.
