DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an envelope processing method and a processing apparatus, and more particularly, to stacking and transporting a predetermined number of envelopes before packing envelopes manufactured by an envelope manufacturing machine. The present invention relates to a processing method and a processing apparatus.

[0002]

2. Description of the Related Art Envelope manufacturing machines capable of continuously manufacturing envelopes have been known. The envelope manufacturing machine includes a feeding device that continuously feeds the raw roll paper, a cutting device that cuts the fed paper, a coating device that applies a predetermined adhesive to the cut paper, and the adhesive. A guide device that bends the coated paper while transporting it to form a bag with a bottom.

[0003] Envelopes manufactured by the envelope manufacturing machine are sequentially discharged in an upright state from a downstream side of the envelope manufacturing machine toward a predetermined transport limit. Here, a large number of conveyed envelopes are gradually applied with a pressing force in a direction orthogonal to the surface direction by the envelopes sent one after another, whereby the pressing force is applied to the bonding area which is the mating surface of the envelopes. Is to be given. Then, the completed envelope is wound with a band of paper in a state where a plurality of sheets, for example, 50 sheets are grouped as one unit, and a plurality of units are collectively stored in a single box.

[0004]

However, the pressing force of each adhesive area of the envelope can be increased as the envelope is closer to the transport limit, but the pressing force on the envelope on the upstream side is relatively larger than this. It will be low. Accordingly, there is a variation in the bonding accuracy, and it is difficult to maintain the bonding accuracy for each envelope uniformly.

[0005]

SUMMARY OF THE INVENTION The present invention has been devised in view of such inconvenience, and an object of the present invention is to maintain uniform adhesion accuracy of each envelope while conveying the envelopes in a predetermined number unit. An object of the present invention is to provide an envelope processing method and a processing apparatus.

[0006]

In order to achieve the above object, an envelope processing method according to the present invention supplies an envelope formed in a bag shape with a bottom one by one in a predetermined direction, and pre-loads the envelope in advance. In an envelope processing method for feeding a set number of sheets to a transport device, the envelopes are supplied to an envelope receiving device in a predetermined posture while rotating the envelopes one by one, and the number of sheets reaches a preset number. And that the next set number of first envelopes are supplied to these envelopes, and at the same time, the envelopes that have reached the set number are supplied collectively to the transport device. I have. By employing such a method, the envelopes can be conveyed in a state in which a predetermined number of envelopes are put together, and subsequent handling can be easily performed.

Further, the envelope processing apparatus according to the present invention supplies an envelope formed in a bag shape with a bottom one by one in a predetermined direction, and supplies the envelopes to a conveying apparatus in a predetermined set number of sheets. In an envelope processing device, a rotating device that rotates envelopes sent from a predetermined envelope manufacturing machine one by one and sends them in a direction of a predetermined posture, and supports the envelope sent from the rotating device, and An envelope receiving device capable of releasing the support at a timing and a transport device for receiving and transporting the envelope whose support has been released are provided.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the above method, it is preferable to adopt a method in which the envelopes supplied to the transport device are transported with a variable pressing force applied to the adhesive area of the envelopes. Thereby, even if the adhesive area of the envelope in the stacked state is thicker than the other areas of the envelope, the pressing force can be kept at an appropriate level, and there is a possibility that defective adhesion may occur in the envelope as a product. It can be effectively avoided.

The rotating device in the envelope processing apparatus includes a shaft disposed in a direction substantially perpendicular to the direction in which the envelope is conveyed, and at least two rotating members supported by the shaft. Slits are formed in the rotating body at equal intervals in the circumferential direction, and the envelopes sent from the envelope manufacturing machine are provided so that they can be inserted one by one so as to straddle between the slits of each rotating body. I have. With such a configuration, the mechanical design of inserting the envelope into the slit at a speed synchronized with the mechanical speed of the envelope manufacturing machine becomes easy, and the speed of the envelope processing can be increased to improve the efficiency.

[0010] Further, between the rotating members, there are provided bars for sequentially scraping the envelopes inserted into the respective slits and dropping them on the envelope receiving device. The envelope inserted into the slit is obstructed by the bar while the rotational position is changing, so that the envelope can be extracted from the slit. Therefore, the envelope can be pulled out from the dynamic rotating body by approaching the static state, and the envelope can be stacked at a certain position without dispersing the envelope.

The envelope receiving device comprises a plurality of plate members capable of supporting the outer edge of the envelope and a cylinder for moving the plate member forward or backward, and the plate member is moved backward or rotated to receive the envelope. It is preferable to adopt a configuration in which the envelope is provided so as to be able to drop on the transport device when the user cancels the operation. When such a configuration is adopted, the envelopes that have reached the set number can be dropped onto the transport device in a united state without losing the posture.

In addition, the apparatus further includes a baffle device capable of moving forward and backward at a position above the envelope receiving device, wherein the baffle device is configured such that when the number of envelopes supplied onto the envelope receiving device reaches a predetermined number, the baffle device is activated. While moving forward on the envelope receiving device and temporarily receiving the envelope sent from the rotating device, the envelope on the baffle plate device is retracted when the envelope receiving device returns to the envelope receiving position to the envelope receiving device. It is configured to deliver. Therefore, even when the envelope receiving member retreats or rotates to drop a predetermined number of envelopes, the envelope plate device is continuously fed until the envelope receiving device returns to the envelope receiving position. Will act temporarily to receive

Further, the baffle plate device includes a temporary envelope receiving plate, and a descent device for lowering the temporary envelope receiving plate when the temporary envelope receiving plate is retracted. With such a configuration, when the temporary envelope receiving plate is retracted, an instant gap can be formed between the envelope on the temporary envelope receiving plate and the temporary envelope receiving plate. When the envelope is retracted, the envelope is prevented from moving backward while the envelope is on the temporary envelope receiving plate, and can be transferred to the envelope receiving device while maintaining a stable stacked state.

The transfer device includes a first transfer device provided at a position below the envelope receiving device, and a second transfer device disposed at a position downstream of the first transfer device. Are provided to be able to move up and down in the vertical direction via a transfer direction switching device. By providing such a switching device, the unfinished envelope in the test operation state can be distinguished and sent out to a different place, so that the finished product and the unfinished product can be prevented from being mixed.

[0015] The second transport device includes a lower transport belt and an upper press belt disposed at a predetermined distance from an upper surface of the lower transport belt. Are arranged in plural rows at predetermined intervals. At this time, it is preferable to provide the pressing force of the upper press belt so as to be individually adjustable. When such a configuration is adopted, even if the overall thickness of the laminate changes variously according to the weighing of the envelope, it is possible to realize belt rotation at a position corresponding to this thickness. Further, even when the bonding area is partially thick, it is possible to secure an appropriate pressing force to the area, and it is possible to stably transfer while maintaining a constant bonding accuracy.

In FIG. 2, the structure on the upper press belt 64 side is omitted to avoid complicating the drawing.

As shown in FIG. 3, the upper press belt 64 is wound around rollers 73 rotatably supported at a plurality of positions along the longitudinal direction of the frame 70.
Each of the rollers 73 is attached to each of three locations along the axial direction of the rotating shaft 75, thereby forming three rows of upper press belts 64. The upper press belts 64 in each row are in contact with the lower transport belt 63. An independent pressing force can be applied to the envelope E which is conveyed in between.

In FIG. 1, reference numeral 100 denotes a control device. The control device 100 allows the user to input the set number of envelopes E described above, and variably sets the position of each part of the device and mutual timing adjustment. It has become.

Next, the overall operation of this embodiment will be described.

The envelope E manufactured by an envelope manufacturing machine (not shown) is sent out at high speed to the rotating body 21 by the rotation of the suction device 11 and inserted into the slits 23, respectively. Each inserted envelope E descends while contacting the bottom with the bar 25 while rotating in the counterclockwise direction, and is received by the envelope receiving device 15 when the slit 23 completely passes through the bar 25 area. . At this time, slit 2
The number of times 3 has passed the sensor 22 is counted. here,
When the set number is set to 50 and set by the control device 100, immediately after the count number of the sensor 23 reaches 50, the baffle plate device 16 is driven and the envelope temporary receiving plate 3 is set.
8 advances to a position below the rotating body 21, and thereafter, the supply of the envelope E to the envelope receiving device 15 is cut off.

At this time, the L-shaped plate members 27 constituting the envelope receiving device 15 are retracted in the direction away from each other, and at the same time, are rotated by a predetermined angle so that the tips of the plate members 28 are at the lower position. Therefore, the envelope E falls in a stacked state on the first transporting device 17 circulating at the lower position.

When the dropping of the envelope E is completed, the L-shaped plate member 27 and the piece-shaped plate member 28 of the envelope receiving device 15 return to the envelope receiving position again. At this time, the envelope temporary receiving plate 38 is in a state where a certain number of envelopes E, which are sent one after another, are stacked in a stacked state. And
The cylinder 42 provided on the base side of the temporary envelope receiving plate 38 operates to instantaneously lower the free end side of the temporary envelope receiving plate 38, and at the same time, the piston rod 40A of the cylinder 40 connected to the link mechanism 39 extends. As a result, the envelope E is temporarily retracted on the envelope temporary receiving plate 38 and transferred to the envelope receiving device 15. Then, while such a cycle is repeated thereafter, the envelope is supplied in units of 50 sheets.

The 50 dropped into the first transfer device 17
The envelopes E are sent to the second transport device 19. In addition,
When the entire apparatus is in the test operation state, an unfinished envelope is sent, so that the first transporting apparatus 17 is maintained in an inclined posture toward the collection box 60 by the cylinder 57 constituting the transporting direction switching apparatus.

In the normal operation state of the apparatus, the envelope E sent to the second conveyor 17 is conveyed between the lower conveyor belt 63 and the upper press belt 64 and is sequentially conveyed downstream. At this time, as described above, the pressing force of the roller 77 is individually adjusted by the spring 80, and thereby an appropriate pressure corresponding to the lamination thickness of the envelope E and the partial thickness of the bonding area is applied.

The envelope that has passed through the second transport device 19 is sent to a predetermined packing step via the next transport path 83.

Therefore, according to such an embodiment, the manufactured envelopes E can be conveyed in predetermined units while counting unmanned, and by connecting to the envelope manufacturing machine, the subsequent processing can be performed. Can be performed in a series of flows.

The configuration of each section of the apparatus according to the present invention is not limited to the illustrated configuration example, and various changes can be made as long as substantially the same operation is achieved. That is, in the present invention, it suffices that the envelopes E are stacked in a predetermined posture and sent out every predetermined number of sheets, and that a constant pressing force can be applied to the envelope being transported. For example, in the above-described embodiment, the rotating device 13 is configured by using the three rotating members 21. However, two or four or more rotating members may be used according to the size of the envelope.

In the above embodiment, the envelope receiving device 15
Although the embodiment in which the envelope E is supplied so as to have a substantially horizontal posture with respect to the above is illustrated and described, the present invention is not limited to this, and if the pressing force against the envelope can be kept constant, The envelope E may be supplied in a state where the envelope E stands upright.

[0039]

As described above, according to the present invention,
While rotating the envelopes one by one, the envelopes are supplied to the envelope receiving device so as to be bundled, and when the preset number is detected, the next set number of the first envelopes is supplied onto these envelopes. Since it is configured such that the set number of envelopes can be supplied to the transporting device while restricting the number of envelopes, a plurality of envelopes can be transported as one unit.

In addition, since the transfer device is configured to be able to transfer while applying a pressing force corresponding to the thickness, it is possible to maintain a good transfer state and to adjust the pressing force to the bonding area, so that the product can be used as a product. It is also possible to avoid the possibility of poor adhesion and the like in the envelope.

Further, according to the present invention, a slit is provided in at least two rotating bodies which are supported on a coaxial line, and envelopes are provided so as to be inserted one by one into the slits, and while the rotating body is rotating. Envelopes come into contact with the bar and are pulled out of the slit, so even if the rotating body is rotating at high speed, it is possible to pull out the envelope in a state close to the stationary state, and a stable stacking on the envelope receiving device It can be extracted to form a state.

Further, since the envelope receiving device is configured to support the outer edge side of the envelope, the operation of dropping the set number of envelopes onto the transport device can be performed very easily.

Further, when the envelope receiving device drops the set number of envelopes, the baffle plate device temporarily receives the envelope, and when the envelope receiving device returns to the envelope receiving position again, the baffle plate device is used. Since the temporary reception of the envelopes is released, continuous envelope supply is possible without stopping the operation of the apparatus, and there is no possibility that the processing efficiency is reduced. Moreover, since the temporary envelope receiving plate constituting the baffle plate device is configured to instantaneously descend when retreating,
The set number of envelopes can be reliably dropped onto the transport device without pulling out the envelopes by this retreat operation.

Further, since the upper press belt constituting the second conveying device is provided so that the pressing force against the envelope can be individually adjusted, the belt circulates at a position corresponding to the thickness of the stacked envelopes. Can be realized, and an appropriate pressing force of the bonding area can be secured, and stable conveyance can be performed.
