Abstract

PROBLEM TO BE SOLVED: To package a relatively thick object to be packaged such as a laminate of paper or the like without being shifted and unfastened. SOLUTION: An object A to be packaged is forcibly pushed into a first reciprocating finger means 3 in contact with a wrapping paper B held approximately vertically by a paper feeder D. The finger means 3 holds a front of the object A together with the sheet B and pulls it onto a conveyer 4A forward while lowering. At this time, a second reciprocating finger means 5 of a post- folding device is inclined forward so that a rear of the object A slides down along a slope. Thus even if there is a large stage between a supply table 1 and the conveyer 4A, impact of drop to the object A is slight, so that a laminate may not be unfastened, and vertical vibration stops soon. Thereafter the second reciprocating finger means 5 moves forward in a horizontal state and folds a rear piece of the wrapping paper B onto a front of the object A.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging apparatus for almost automatically packaging a relatively large plate-shaped rectangular object to be packaged (for example, a stack of various types of cardboard).

[0002]

2. Description of the Related Art The present applicant has filed a Japanese Patent Application No. 63-52357.
(Japanese Patent Publication No. 6-29051), Japanese Patent Application No. 6-338.
No. 136 (JP-A-8-175506) and the like have proposed a packaging apparatus for automatically packaging an article to be packaged in a plate-like rectangular parallelepiped shape. The basic configuration of this packaging device is
A supply table on which the substantially plate-shaped rectangular solid to be packaged is placed horizontally,
A wrapping paper vertical holding means for holding the wrapping paper one by one in a substantially vertical state at a front end portion of the wrapping object on the supply table, and a wrapper forcedly pushed in contact with the wrapping paper in the vertical state. First reciprocating finger means for holding the object together with the wrapping paper and transporting the same forward while simultaneously folding the front paper piece of the wrapping paper rearward on the object to be packaged and performing edge folding on both sides; A carrier table having a step larger than the thickness of the package and receiving the packaged object transferred together with the first reciprocating finger means, and conveying the first reciprocating finger means from the height of the supply table during the forward movement Elevating means for lowering to the height of the table and raising the height from the height of the carriage to the height of the supply table at the time of reciprocation; and Place the back side of the wrapping paper on the dropped A second reciprocating finger means for performing folding and on both sides edge folded towards, and attaching means for attaching the stacked portion of the front piece of paper and the rear paper folded,
Sticking means for sticking together the laminated portions of the paper pieces at the ear portions of the folded wrapping paper.

[0003]

In the packaging apparatus having the above structure, when the object to be packaged is pushed into the first reciprocating finger means, the first reciprocating finger means is placed above the second reciprocating finger means. Waiting in a stacked state. For this reason, it is necessary to design the apparatus such that the step between the supply table surface and the transfer table surface is equal to or greater than the thickness of the article to be packaged. When the first reciprocating finger means moves forward while nipping the object to be packaged and the wrapping paper, the first reciprocating finger means is lowered by the elevating means from the supply table to the transfer table. At this time, the front end of the packaged object is held by the first reciprocating finger means, but the rear end of the packaged object is in a free state where it is not held. When it does, it vibrates in a wavy manner due to the impact. When the level difference between the supply table and the transfer table is relatively small, the amplitude of the vibration is small and quickly converges. However, when the level difference is large, it takes time until the vibration stops, and after the elapse of a short time, the next process In other words, the second reciprocating finger means must be used to fold the rear sheet of the wrapping paper, and the work efficiency is greatly reduced. An even greater problem is that if the packaged object is a laminate of paper or the like, and the impact of the drop is large, the laminate will collapse even if the front of the packaged object is sandwiched by the first reciprocating finger means, That is, the packaging operation cannot be continued.

Therefore, in the conventional packaging apparatus, the step between the supply table and the transfer table is designed to be small so that vibration at the time of falling and collapse of the laminated body do not cause a problem. For this reason, there is a problem that the upper limit of the thickness of the wrapped object is limited, and a thick object cannot be wrapped.

Further, in the above-mentioned conventional packaging apparatus, when the object to be packaged becomes thicker, when the second reciprocating finger means is pushed into the object to be packaged from the rear in order to perform the later folding, the wrapping paper at the rear end is formed. There is a problem that the corner at the lower rear end of the packaged object is not folded back cleanly due to loosening, resulting in a rounded shape.

Further, in the above-mentioned conventional packaging apparatus, edges are folded on both sides by using two upper and lower edges for horizontal folding which are fixed to the first and second reciprocating finger means. I have. Since the height of the edge of the edge needs to be changed according to the thickness of the packaged object, conventionally, the mounting height of the two edge-folding fingers is different (for example, every 5 mm).
A plurality of finger members are prepared, and the finger members are exchanged according to the thickness of the article to be packaged. For this reason, every time the thickness of the article to be packaged changes, the troublesome work of replacing the finger member must be performed, which has been one of the causes of a reduction in the efficiency of the packaging operation.

By the way, in the above-mentioned packaging apparatus, a product stock table for carrying out is installed at the end of the carrier table, and the packages completed on the carrier table are sequentially stacked on the product stock table. However, in the method of sequentially loading the packages transferred by the transport table from the top, even small-sized (area) packages that can be loaded in a plurality of rows on the product stock table are loaded in one row. I can only do it. In this case, the product stock table cannot be effectively used, and the product stock table must be replaced frequently, which deteriorates the work efficiency.

Therefore, conventionally, an unloading device capable of stacking in two rows is further provided at the end of the transfer table. The unloading device includes a conveyor provided with a plurality of poles extending further in front of the transport table and supporting the package on the upper surface, and vertically moving at the leading end position of each package in the two-row stacking in the transport direction of the conveyor. The product stock table is installed at a predetermined position below the conveyor. When loading on the front side of the double-row loading (far side from the carrier), the stopper at the leading end of the package is lowered to a height very close to the conveyor surface, and the package is placed on the conveyor pole. It is transported forward. The package on the conveyor comes into contact with the stopper and stops, and when the pole supported on the lower surface passes through, the support is lost and the package falls downward. As a result, the packages are stacked at predetermined positions on the product stock table. When loading on the rear side (closer side to the carriage) of double-row loading,
When the rear stopper is lowered and the conveyor similarly passes through, the package falls to a predetermined position on the rear side of the product stock table.

However, in the above-described unloading device, the conveyor is disposed so as to cover the product stock table, and since the conveyor driving device blocks both sides of the product stock table, the product stock table is moved to the side. Is difficult. For this reason, the replacement of the product stock table is troublesome and the working efficiency is poor. In addition, it is necessary to secure a wide space for installing the unloading device and a space for moving the product stock table. Furthermore, since the package falls with a height higher than the thickness of the conveyor, there is a problem that the package is easily collapsed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a first object of the present invention is to package objects to be packaged thicker than a conventional packaging apparatus without lowering the working efficiency. It is to provide a packaging device which can be used.

It is a second object of the present invention to provide a packaging apparatus which can fold a rear end portion of a thick packaged object with good appearance.

It is a third object of the present invention to provide a packaging device with high work efficiency, which can reduce the time and labor required for replacement of a finger for edge folding.

A fourth object of the present invention is to provide a packaging apparatus provided with a carry-out device capable of freely stacking a single row and a plurality of rows on a product stock table according to the size of an article to be packaged. It is in.

[0023]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the packaging apparatus according to the first aspect of the present invention, the article to be packaged placed on the supply table is forcibly applied to the first reciprocating finger means of the front folding apparatus together with the vertical wrapping paper. , And the first reciprocating finger means grips the front of the article to be packaged and the wrapping paper to transfer it forward. When the lifting / lowering means lowers the first reciprocating finger means from the height of the supply table to the height of the transfer table, the front of the packaged object is lowered to the transfer table. With the transfer to the front, the packaged object passes over the upper part of the second reciprocating finger means. At this time, since the upper part of the second reciprocating finger means is inclined from the supply table side to the transfer table side, The rear part of the packaged object slides down from the supply table to the transfer table along the inclination. For this reason, even when the rearmost part of the package reaches the transport table, the impact of the descent is small, and the vibration of the rear part of the package is small and converges in a very short time. In addition, even if the packaged object is a laminate, collapse of the load does not occur. When the object to be packaged has passed over the upper part of the second reciprocating finger means, the inclination quickly returns to the horizontal state, and the second reciprocating finger means moves horizontally forward to move the rear part of the object to be packaged. I will do it later.

[0024] As an example of the structure, the second reciprocating finger means is rotated around a shaft portion extending to the rear side thereof, and when the packaged object passes through the upper part, it is moved downward to the transfer table side. The structure is simplified if the upper surface is inclined and the upper surface is inclined from the supply table side to the transfer table side. After the object to be packaged passes over the inclined second reciprocating finger means, the second
Is returned to a horizontal state, and the horizontal reciprocating finger means folds a rear piece of wrapping paper positioned forward in front of and above the article to be packaged while moving horizontally forward.

When the height of the upper surface of the second reciprocating finger means is adjusted in accordance with the thickness of the article to be packaged, lowering the mounting height of the upper plate causes the upper plate and the supply table to be lowered. The height and the step are large. Therefore, in such a case, one side is fixed at approximately the height of the supply table above the upper surface plate of the second reciprocating finger means, and the edge facing the side is the second reciprocating finger means. It is preferable to provide a guide plate that tilts downward in accordance with the rotation of. The guide plate acts as a sliding plate member extending from the supply table to the transfer table, and can gently slide down the article to be packaged regardless of the mounting height of the upper plate.

The rear folding member, which is provided on the carrier table so as to be able to stand substantially vertically upward, can be horizontally moved so as not to hinder the transfer when the articles and the wrapping paper are transferred from the supply table to the carrier table. Will be retained. Then, when the packaged object is transferred onto the carrier table by the first reciprocating finger means, it stands up. Thereby, the wrapping paper is folded upward along the right-angled corner at the rear lower end of the wrapped object. Therefore, when the second reciprocating finger means subsequently advances from the rear,
The rear end of the package is folded neatly.

Further, if the first and second reciprocating finger means are provided with two edge-folding finger plates whose intervals can be changed up and down, before the packing operation of the articles to be packaged having different thicknesses. The preparatory work is completed only by adjusting the interval between the edge folding finger plates according to the thickness. This allows
The trouble of replacing the finger plate, which has been conventionally performed, becomes unnecessary, and the efficiency of the packaging operation is improved. The two edge-folding finger plates may be provided, for example, so as to be slidable up and down within a predetermined range so that their positions can be fixed by locking members such as screws.

Further, if the lower edge folding finger plate is fixed to the lower surface plate and the upper edge folding finger plate is moved up and down integrally with the upper surface plate, the upper surface plate can be moved in accordance with the thickness of the article to be packaged. When moved up and down, the interval between the upper edge folding finger and the lower edge folding finger is also automatically adjusted to an interval suitable for the thickness of the packaged object, so that the adjustment work is further simplified. You.

When the thick packaging object is packed in the packaging apparatus according to the first aspect of the present invention, the interval between the upper and lower edge folded fingers is widened, so that the wrapping paper pieces on both sides bite into the gap, and May not be able to fold the edge. However, when the plate member is provided inside the upper edge folding finger plate, the plate member is provided when the first reciprocating finger means sandwiches the packaged paper with the article to be packaged or the second reciprocating finger means is covered. When the package and the wrapping paper are gripped from behind, the wrapping paper on the side is prevented from loosening in the space between the upper and lower edge folding finger boards, so that the edge can be folded properly and the package looks good. Finish.

In the packaging apparatus according to the second aspect of the present invention, when the package, which has been packaged, reaches the end of the carrier, the extruded plate is installed behind the package, and the extrusion drive mechanism moves the extruded plate forward. The package is pushed and moved to a predetermined position on the carry-out table by sliding. Next, with the stopper retracted, the table drive mechanism horizontally moves the carry-out table forward. After the forward movement, the stopper is extended to the rear of the package, and the carry-out table is horizontally moved back. The package on the carry-out table abuts the stopper and stays at that position, and when the carry-out table moves back, it loses support and falls downward. The falling distance is extremely small because only a small margin is added to the thickness of the carry-out table, and collapse of the load due to falling hardly occurs.

In the case of performing two-row stacking in the transfer direction, the extruding plate pushes and moves the first package to a predetermined position in front.
Next, the extruding plate pushes and moves the second package to a predetermined rear position (a position aligned with the first package). Then, after the two packages are aligned on the carry-out table, the carry-out table moves horizontally, and drops the two packages as described above.

Accordingly, prior to the start of the packaging operation, the intervals between the edge folding fingers 34a and 34b on both sides are adjusted according to the width of the article to be packaged. The mounting height of the lower edge folding finger 34 b is fixed to the bottom plate 32, while the upper edge of the upper edge folding finger 34 a is fixed to the finger plate 31. Therefore, when the position of the finger plate 31 is adjusted according to the thickness of the article to be packaged as described above, at the same time, the upper edge folded finger 3
The mounting height of 4a also changes, and both edge folding fingers 34a,
The interval of 34b is appropriately adjusted.

As shown in FIG. 9, the upper edge folding finger 34a is connected to a horizontal plate member 341 and a vertical member 3 which is vertically inside.
42. The upper edge of the horizontal plate member 341
A suitable convex portion 343 formed on the upper surface of the
When the packaged object is thick, the upper edge folding finger 34a and the lower edge folding finger 34b
And the distance between the two fingers 34
In the gap between a and 34b, the side portion of the wrapping paper is slackened and swells outward, so that it is not possible to perform edge folding properly. Therefore, in the present apparatus, the vertical member 342 presses the side of the wrapping paper at the time of edge folding, so that the edge of the wrapping paper is eliminated and the edge folding can be performed properly. The vertical member 34
The entrance side of 2 has a shape inclined outward to facilitate the insertion of the packaged object.

The height of the vertical member 342 of the upper edge folding finger 34a is preferably changed according to the thickness of the article to be packaged. Then, the finger plate 31 is removed from the main body 30, and the upper edge folding finger 34a is removed.
Can be easily removed upward, and a plurality of edge-folding fingers 34a having different heights of the vertical members 342 are exchanged. Even in such a case, since the vertical member 342 is only intended to press the wrapping paper on the side of the article to be packaged, it is usually sufficient to prepare the edge folding fingers 34a having about two or three kinds of heights. It is.

As shown in FIG. 8 (b), the side plates 37 on both sides of the first reciprocating finger means 3 are vertically elongated oval holes 3.
A pair of pins 36b slidably fitted to 6a allows the sliding plate 36 to be vertically reciprocated. When the cylinder rod of the air cylinder 364 fixed inside the sliding plate 36 is extended, the first reciprocating finger means 3 is pushed up to the highest position, and when the cylinder rod contracts, the first reciprocating finger means 3 is moved to the lowest position. Go down to position. The sliding plate 3
8 is slidable back and forth along a slide bar 361 as shown in FIG. 8B, and is fixed in the middle of an endless chain 363 driven back and forth by a servomotor 362, and driven by the endless chain 363. First
Reciprocating finger means 3 is driven to reciprocate back and forth along the slide bar 361.

The finger plate 31 has a limit switch 31
1, the packaged object A is wrapped with the wrapping paper B as shown in FIG.
At the same time, when the first reciprocating finger means 3 is forcibly pushed into the U-shaped space, the limit switch 311 is operated. Then, in response to this signal, the encoder connected to the finger servomotor in the driving device 35 sets the stop position calculated based on the dimensions (thickness) of the packaged object input by the operator in advance. Is detected and the servomotor is stopped. As a result, the front portion of the packaged object A is sandwiched together with the wrapping paper B by the lower end of the rod 351 and the bottom plate 32 which expand and contract by the rotational driving force of the servomotor.

After the clamping, the first reciprocating finger means 3 pulls the package A and the wrapping paper B on the front carrier 4A by the operation of the servo motor 362. At the time of the above insertion, the wrapping paper B is pulled and released from the suction means 25. By the action of the finger plate 31 with its front paper B ₁ is folded backwards onto the packaged articles A, paper projecting to the left and right at the same time the edge folding for fingers 34a, is folded edge by 34b.

The second reciprocating finger means 5 is shown in FIG.
As shown in FIG. 11A and FIG. 11, a main body 50 is provided in which a horizontal finger plate 51 on the upper surface and a vertical push plate 53 on the rear end are assembled in a substantially L-shape that is open frontward. Edge-folding fingers 54a and 54b are slidably provided in the width direction on both left and right sides of the lower portion of the finger plate 51, similarly to the first reciprocating finger means 3. The finger plate 51 and the upper edge-folding finger 54a are provided. And can move up and down integrally. The rear portions of the side plates 57 on both sides of the main body 50 are pivotally attached to sliding plates 56 provided on both sides by shaft portions 55, and the lower end of the cylinder bar of the air cylinder 58 is fixed below the front portion of the side plates 57. I have. When the air cylinder 58 contracts the cylinder bar, the main body 50 of the second reciprocating finger means 5 moves to the shaft portion 5.
5 and is held in a horizontal state as shown in FIG. Conversely, when the air cylinder 58 extends the cylinder rod, the main body 50 is pushed down around the shaft 55 and tilts forward (the front carrier 4A) as shown in FIG. 10B.

The second reciprocating finger means 5 is also provided by the first
As in the case of the reciprocating finger means 3, the mounting height of the finger plate 51 on the upper surface is adjusted according to the thickness of the article to be packaged. Therefore, when the mounting position of the finger plate 51 on the upper surface is lowered,
The step between the supply table 1 and the finger plate 51 becomes large, and when the main body 50 is tilted downward as shown in FIG. 10B, the edge of the finger plate 51 is lowered to below the upper surface of the transfer table 4A. Would. In this state, if the packaged object A pulled from the supply table 1 slides down along the upper surface of the finger plate 51, there is a possibility that the stacked body may collapse.

Therefore, in the present apparatus, the guide plate 5 having an appropriate width is provided at the upper end of the frame 59 behind the main body 50 which moves in the axial direction.
92 is hinged so as to cover the main body 50. The guide plate 592 is held substantially horizontally above the upper finger plate 51 when the second reciprocating finger means 5 is in a horizontal state, and tilts in response to the second reciprocating finger means 5 tilting downward. . At this time, the edge of the guide plate 592 on the unfixed side contacts the upper surface of the front carrier 4A or abuts on an appropriate locking piece near the upper surface to restrict the inclination. It stops near the height of the upper surface of the transfer table 4A. Therefore, regardless of the mounting position of the finger plate 51, the guide plate 59
Numeral 2 functions as an inclined connecting plate that extends from the supply table 1 to the transfer table 4A.

The main body 50, the air cylinder 58, etc.
6 is mounted on a fixed slide 564, and the slide 5
64 is slidably held back and forth by a slide bar 561 laid back and forth like the first reciprocating finger means 3, and is fixed in the middle of a chain 563 driven endlessly by a motor 562. . The chain 5
By the drive of 63, the second reciprocating finger means 5 is reciprocated back and forth.

The second reciprocating finger means 5 is stacked below the first reciprocating finger means 3 as shown in FIG. At this time, the air cylinder 5
Due to the extension of the cylinder rod 8, the main body 50 and the guide plate 592 of the second reciprocating finger means 5 are inclined downward as described above. While the first reciprocating finger means 3 sandwiches the front end of the packaged object A and the wrapping paper B and pulls forward, the air cylinder 364 operates to operate the first reciprocating finger means 3. From the height of the supply table 1 to the height of the front transfer table 4A. Thereby, as shown in FIG. 4, the first reciprocating finger means 3 sandwiches the front end portion of the packaged object A and the wrapping paper B and lands on the front carrier 4A. The rear end slides down on the inclined guide plate 592. Therefore, the packaged object A does not have a large drop impact and does not collapse even if it is a laminated body.

When the entire packaged object A moves onto the front carrier 4A, the air cylinder 58 expands and contracts the cylinder bar, and holds the second reciprocating finger means 5 in a horizontal state. At this time, the front surface of the second reciprocating finger means 5 is
And wrapping paper B. At this time, at the same time, as shown in FIG.
The rear folded plate 43 installed between the first and second reciprocating finger means 5 stands upright. The rear folded plate 43 is
Package A transported by first reciprocating finger means 3
Is provided at a position immediately after the rear end of the package A when stopped. Therefore, when the rear folded plate 43 stands upright, the wrapping paper B at the rear end of the packaged object A is folded vertically upward.

Then, as shown in FIG. 5, with the start of the forward movement of the second reciprocating finger means 5, the finger plate 51 moves forward along the rear upper surface of the packaged object A, and
₂ is folded forward by the finger plate 51, and the left and right protruding paper pieces at the rear are edge-folding fingers 54a, 5a.
The edge is folded by 4b. In particular, when the object to be packaged A is thick, if only the second reciprocating finger means 5 is pressed from behind, the wrapping paper at the rear end is loosened and the rear lower corner cannot be folded neatly. When the second reciprocating finger means 5 is pressed after being turned up once by 43, the corner can also be neatly folded at a right angle. When the second reciprocating finger means 5 moves forward, the front carrier 4A
A gap is formed between the wrapping paper 1 and the supply table 1, and the suction means 25 of the wrapping paper vertical holding means 2 moves up and down during this time.

Above the rear part of the front carrier 4A, a tape sticking means 8a of the body sticking device H is attached so that the sticking direction is perpendicular to the traveling direction of the packaged object A. The tape affixing means 8a is folded by the first and second reciprocating finger means 3 and 5 and each finger plate 3

[0059] In this case, when bonding the adhesive tape to the end portion of the side paper B ₂ after being folded, the length of the packaged articles A is first reciprocating finger means 3 and the second reciprocating finger means 5 In the case where the length is longer than the total length of the respective finger plates 31 and 51, the tape attaching means 8a can be lowered between the finger plates 31 and 51. If the length is close to or shorter than the total length of the finger plates 31 and 51, the tape applying means 8a cannot descend between the finger plates 31 and 51. Therefore, in the present apparatus, as shown in FIG.
The retainer plate 81 of the end portion of the rear paper B ₂ adjacent the taping unit 8a is provided on. The size is determined based on the input product dimensions, and if it is determined that the tape applying means 8a cannot be lowered between the finger plates 31 and 51, the finger plate 51 of the second reciprocating finger means 5 retreats and the tape is applied. the retainer plate 81 faster than drop operation means 8a is pressing the end of the rear paper B ₂ operates. Thereafter, the bonded sealing the front paper B ₁ and the rear paper B ₂ at tape taping unit 8a is lowered.

The front conveyor 4A is provided with a belt conveyor 41 in its longitudinal direction. When the body A of the packaged object A is completed, the first and second reciprocating finger means 3, 5 are moved to the packaged object. A is released and moved back, and the article to be packaged A is conveyed by the belt conveyor 41 and the belt conveyor 42 of the rear conveyor 4B, and moves to the both-end folding means 6 and the tape sticking means 8b of the next step of the wrapping paper. . At the time of the backward movement, the first reciprocating finger means 3 is pushed upward by the air cylinder 364 and returns above the packaged object A. On the other hand, the second reciprocating finger means 5 retreats horizontally as it is.

In the present apparatus, between the front carrier 4A and the rear carrier 4B, a transfer plate 411 having substantially the same height as the belt conveyors 41 and 42 of the front carrier 4A and the rear carrier 4B is provided. ing. Since the inclined plate 613 of the binaural folding means 6 described later is movable on the crossover plate 411, the distance between the binaural folding means 6 of the wrapping paper and the tape affixing means 8b can be freely adjusted to conform to the product dimensions. It is possible to turn both ears back and tape.

As shown in FIG. 12, the binaural turning means 6 provided at the end of the rear carrier 4B is used to drive a horizontal upper plate 611 moving toward the center of the rear carrier 4B on both sides. A folding member 61, left and right parallel folding plates 62 vertically suspended inside the folding member 61, and a folded portion of the folding member 61 provided between the folding members 61 and 62. And a supporting member 63 which is supported by being pressed from the side. An inclined plate 613 is provided at the rear end of the upper plate 611.
Are hinged, and the free end of the inclined plate 613 is
1 and makes a gentle slope. FIG.
As shown in FIG. 14, the upper plate 611 is configured to swing inward around the shaft 615 by the driving device 64, and the entire folding member 61 moves in the direction of the center of the rear transport table 4 </ b> B.

As described above, the article to be packaged A advances, and the protruding ears B ₃ on both sides of the wrapping paper B are folded over the crossover plate 4.
After passing over the upper plate 11, the inclined plate 613 rises upward and faces further upward, so that the upper plate 611 stands upright. Stop the packaged articles A comes to a predetermined position of the turnup members 61, then the folded plate 62 is lowered along the side of the packaged articles A, folding a protruding ear portion B ₃ which is erected substantially vertically. After the folding plate 62 is raised, the entire folding member 61 moves inward. At this time, the folding member 61 is pivoted inward about the shaft 615 by the driving device 64, and the upper plate 611 is raised. while folding the B ₃ to the upper surface of the packaged articles a pressing. Note that the auxiliary member 63 assists folding by pressing the side of the packaged object A.

[0064] Then, taping means 8b is lowered disposed inside the Ryomimiorikae means 6, all packaging operation to seal the ends of the protruding ear portion B ₃ is completed. The tape sticking means 8b may be the same as the tape sticking means 8a, and is desirably a device already invented by the present applicant. The laminating direction of the tape laminating means 8b coincides with the traveling direction of the packaged object A, and the tape laminating means 8b is disposed on the left and right sides one by one.

In the above description, the tape sticking means 8a and 8b are used for the body sticking device H and the horizontal sticking device I, respectively. However, other sticking methods can be used. As an example thereof, an adhesive, an adhesive applying means for dripping or spraying an adhesive such as a heat-melted brazing material is provided, and after the adhesive is applied to one of the bonding portions of the wrapping paper B, the wrapping paper is And stick them together as if pressing. According to such a bonding method, since the swelling of the bonded portion can be made thinner than in the case of using the adhesive tape, for example, only the bonded portions on both sides rise when the packaged product is laminated. Therefore, the central portion is not depressed.

Next, a description will be given of an unloading device for arranging and stacking the packages completed in the above-described steps on a product stock table for unloading. FIG. 15 is a side sectional view of the carrying-out device of the present embodiment.

The carry-out device of the present embodiment comprises a transfer device J comprising a flat carry-out table 100 and a drive device for horizontally reciprocating the carry-out table 100 to a position above a product stock table 140 in front thereof; an extrusion apparatus K provided with a pushing plate 110 for extruding moving packaging a ₁ which has been conveyed to a predetermined position on the unloading table 100 by backward transfer table 4B, associated with reciprocating movement of the unloading table 100 in outlet port 130 configured to package a ₃ from the stopper 120. to fall down Te. The product stock table 140 installed outside the unloading port 130 of the unloading device is configured to be movable up and down in the same manner as the table lifter 10, and the package C
Each time is stacked on top.

The extrusion plate 110 of the extrusion device K has two pulleys 1.
11, and is slid back and forth by the rotational driving force of a motor 113.
One end of the push-out drive mechanism 116 is rotatably fixed to a shaft 114 fixed to a base of the unloading device.
And is suspended by a suspension chain 115 at a location away from the vehicle. When the air cylinder 117 fixed above pulls the extrusion drive mechanism 116 via the suspension chain 115, the extrusion drive mechanism 116 rotates about the shaft 114 as a fulcrum,
Pushing plate 110 is retracted upward to a position which is not an obstacle to passage of the package A _1.

FIG. 16 is a side view (a) and a top view (b) showing the detailed structure of the transfer device J. Unloading table 1
00 A slide frame 1 that extends rearward on both sides
01 is provided, and is attached to the machine base by being sandwiched by two pairs of rollers 102 in front and behind. Slide frame 10
1 is provided with a toothed rack 103, and the carry-out table 100 is slid forward and backward by the meshing between the pinion 104 and the rack 103, which are rotated via a chain 105 by the rotational driving force of a motor 106. Is done.

In the above-described unloading device, it is possible to switch between single-row packaging and double-row packaging of relatively small-sized packages. First, the operation when performing one-row stacking will be described with reference to FIG. Packaging A ₁ backward conveying base 4B
When the extruded plate 1 is transferred from the
10 is towed by the suspended chain 115 lowermost to a position higher than the upper surface of the package A ₁ of the last portion to returned and extruded drive mechanism 116 pushing board 110 by a chain 112. Packaging A ₁ the packaging is finished ends of the rear carrying table 4B (i.e. end point of the transport by the belt conveyor 42)
, The suspension chain 115 is fed out and the extrusion drive mechanism 116 is lowered to a horizontal state. At this time, the extruded plate 1
Numeral 10 is arranged as a whole so as to always be located behind the package. Then, pushing plate 110 is extruded moved position (for example, the position of A ₂₎ to packages from behind in response to product dimensions entered.

[0071] Then, out table 100 by the motor 106 to slide horizontally forward while placing the package A ₂ on the top surface. Stopper 120 is adapted to be rotated about the shaft portion 121 by a driving device (not shown), the stopper 120 when the unloading table 100 is moved forward to the front does not contact the package A ₂ on unloading table 100 It has been retracted upward to the position. In addition, the product stock table 140 is sequentially lowered with an appropriate distance between the upper surface of the package C already loaded and the lower surface of the unloading table 100 (for example, such a distance that the unloading table 100 does not contact even if the unloading table 100 vibrates up and down). Is set to

The carry-out table 100 is the product stock table 14
If it protrudes to above the 0 stops at a predetermined position (broken line position), the stopper 120 is descended close the rear of the package A _3. Rearmost unloading table 100 is horizontally backward to when to return to the original position該搬out package A ₃ on the table 100 is in contact with the stopper 120, unloading table below leaving a package A ₃ to the position Only 100 returns. Thus, package A ₃ falls onto packaging C stacked on the lower side of the product stock table 140. This drop distance is very small because it is simply the sum of the thickness of the carry-out table 100 and the above-described distance, and the dropped packages are stacked neatly with little displacement.

Next, the operation in the case of performing two-row stacking in the traveling direction of the package will be described with reference to FIG. Packaging L ₁ that has reached the end of the backward conveying base 4B is packaged similarly to the case of one row loading described above is extruded moved from the rear by pushing plate 110 reaches a predetermined position (position of the L _2). Thereafter, the extruding plate 110 is returned to the last position again, and the extruding drive mechanism 116 stands by while being pulled upward by the suspension chain 115. The following package is extruded driving mechanism 116 reaches the end of the backward conveying base 4B is lowered, pushing plate 110 is moved to the position L ₃ Press the package from the rear. As a result, the two packages L ₂ and L ₃ are arranged closely on the carry-out table 100 in the traveling direction.

When the two packages are prepared, the carry-out table 100 is horizontally moved in a state where the stopper 120 is rotated upward and the carry-out port 130 is opened in the same manner as in the case of the single-row stacking described above. 120 out table 100 after closes the back of the package L ₅ of the rear side is horizontally backward. Therefore, the packages L ₄ , L ₅ arranged on the carry-out table 100
Falls on the product stock table 140 below.

In this unloading device, the moving amount of the extruding plate 110 is controlled according to the input product dimensions. For this reason, packages of various sizes equal to or smaller than a predetermined size within a range capable of being stacked in two rows can be stacked in two rows on the product stock table 140 in an orderly manner. Further, since the drop position of the package is determined by the position of the stopper 120, the product stock table 140
By appropriately changing the installation position of the package, the package can be loaded at a predetermined position on the product stock table 140.

The above-described embodiment is merely an example, and it is apparent that modifications and modifications can be made as appropriate within the scope of the present invention.

[0077]

As described above, in the packaging apparatus according to the first aspect of the present invention, when the first reciprocating finger means of the front folding apparatus grips and transports the front part of the article to be packaged, The second reciprocating finger means is inclined from the supply table to the transfer table, and the rear part of the packaged object slides down along the inclination.
For this reason, even if the height difference between the supply table and the transfer table is large, the impact of the fall of the packaged object is small. Therefore, the vertical vibration at the time of transfer is small and the vibration can be quickly settled even in the case of a large-size packaged object, so that the post-folding operation can be quickly performed after the transfer to the carrier, thereby improving the efficiency of the packaging operation. be able to. Further, even if the article to be packaged is a laminate of thin members such as paper, the laminate does not collapse due to impact. For this reason, it is possible to increase the level difference between the supply table and the transfer table, and to perform packing up to an object to be packaged which is thicker than the conventional apparatus.

Further, since a member is provided for vertically folding the wrapping paper piece at the rear end of the wrapped object immediately after the wrapped object is transferred onto the carrier, the wrapped object is relatively thick. Also, the wrapping paper at the rear end can be folded forward without being loosened. For this reason, the corner at the lower end of the rear end of the package can be neatly folded at a right angle.

Also, since the mounting height of the two edge-folding finger plates can be adjusted, the time required to replace the edge-folding finger member according to the thickness of the packaged object as in the related art is reduced. Can be reduced, and the work efficiency in performing the packing work of the articles to be packed having various thicknesses can be improved.

Further, the upper finger plate of the two upper and lower finger plates for edge folding can be moved up and down integrally with the upper finger plate for front fold or rear fold. By adjusting the height of the upper finger plate for the front or rear fold, the edge fold can be adjusted at the same time, and the efficiency of the packaging operation is further improved.

In the packaging device according to the second aspect of the present invention, the carry-out device is connected to the rear portion of the transport device, and after the package is pushed out to a predetermined position on the thin plate-like carry-out table, the carry-out table is connected to the product. After the package is horizontally moved upward and the stopper stops the retreat of the package, the carry-out table is moved back to drop the package downward. For this reason, since the falling distance of the packages is extremely short, the packages can be stacked neatly without collapse. In particular, even in two-row loading, it can be stacked neatly without collapse of the load.

Further, since the carry-out table only protrudes above the product stock table, there is no need to install a conveyor driving device or the like on the side of the product stock table as in the prior art. Can be moved easily, and the work of replacing the product stock table can be performed efficiently. Furthermore, since the installation area of the unloading device is small, the space can be saved.
