Abstract

PURPOSE:To positively prevent multi-sheet feeding in a feed device for plywood, etc., by providing a run-off preventing body so that it abuts on the end face of the front side of a number of laminated sheet-like articles. CONSTITUTION:When a band-belt 26 is driven, a sheet D of the lowermost layer of laminated corrugated board-sheets D is dragged by the belt 26 and moved, and the sheets are advanced while slippages are formed between the sheets of each layer. The sheets pass through between the feed surface of the belt 26 and a regulating body 48. At this time, the sheets D lift the regulating body 48 to a position where an upward force lifting the regulating body 48 and a downward force due to the dead weight of the regulating body 48 are in balance. Further. a guide face 49 of the regulating body 48 abuts against the end face of the front side of the sheets D to block the advance of the sheets D. Thus, the sheets D are separated one by one with a gap in sequence. By this constitution, the sheets can be positively separated and supplied.

Description

Detailed Description of the Invention (Objective of the Invention) <Industrial Application Field> The present invention relates to a conveying device for sheet-like articles that continuously feeds corrugated sheets, plywood, and other sheet-like articles one by one from a stacked state. It is something.

<Background of the Invention> For example, at a manufacturing site for corrugated paper cartons, etc., when sending corrugated sheet material of a predetermined size to a so-called machine for processing such as cutting or printing as appropriate, it is necessary to accurately produce only the number of sheets that meet the requirements of the machine. must be accumulated. For this reason, in actual work, a large number of cardboard sheets are piled up in a preliminary stacked state, and each sheet is sent out continuously in accordance with the work speed, so that a fixed number of sheets are always accumulated in the storage area of 1M. I try to do that. The conventional method for this kind of transfer is to stack a large number of sheet-like articles in a slightly inclined state and run a belt conveyor, which is a supporting member on the lower surface, in the conveying direction. The sheets are taken out in order by being sent forward. However, in recent years, with the diversification of logistics systems, bulk transportation by automobiles has become more common, and in such cases, cardboard boxes with higher surface friction are required in order to prevent cargo from collapsing. . For this reason, the mutual friction coefficient of the corrugated cardboard sheets used as raw materials is also larger, and in the case of the above-mentioned method, which assumes a constant slippage between the sheets, the sheets are not taken out smoothly one by one, and the sheets overlap. Sometimes they were sent away.

Technical matters for which development was attempted> The present invention was made in view of this background, and
A new sheet-like article transfer device that prevents overlapping sheet-like articles from being fed to the machine by providing a device that restricts sheet-like articles that tend to be fed in an overlapping state in the conveying direction of the sheet-like articles. This is an attempt at development.

(Structure of the Invention) (Means for Achieving the Object) In other words, the first invention of the present application is a conveying device for sheet-like articles, in which a large number of sheet-like articles are stacked, and a support member on the lower surface of the sheet-like articles is moved forward in the conveying direction. In this apparatus, the sheet-like articles that are in contact with the sheet-like articles are sequentially shifted from below in the transport direction and sent out separately, and the front end surface of the stacked sheet-like articles is provided with an outflow prevention body that is in contact with the sheet-like articles. It is admonished as a characteristic that it has been established.

In addition to meeting the above-mentioned requirements, the second invention of the present application is a sheet-like article transporting device, which is characterized in that the installation position of the outflow prevention body is adjustable.

Furthermore, in addition to the above-mentioned requirements, the third invention of the present application is a sheet-like article transfer device, in which the outflow prevention body has a smooth guide surface in front at least below the surface of contact with the sheet-like article. It is characterized by the following.

Furthermore, in addition to the above-mentioned requirements, the fourth invention of the present invention, a sheet-like article transfer device, is characterized in that the support member is capable of being lifted forward.

Furthermore, in addition to the above-mentioned requirements, the fifth invention of the present application is a conveying device for a sheet-like article, in which the supporting member is characterized in that the feeding center is in a raised state.

These inventions are intended to distantly achieve the above object.

<Operation of the Invention> The sheet-like article transporting device of the present invention is provided with a flow-out prevention body in contact with the front end face of a large number of stacked sheet-like articles, so that sheet-like articles can be prevented from flowing out in an overlapping state. It can be prevented.

Further, by making the installation position of the outflow prevention body adjustable, appropriate adjustments can be made depending on the shape of the sheet-like article, etc.

Furthermore, if the flow-out prevention body has a smooth guide surface in the front at least below the contact surface with the sheet-like articles, it will prevent the stacked sheet-like articles from touching the support member in the process of falling downward. Coupled with the transfer of the sheet-like article that is in contact with it, the upper end of the sheet-like article in the transfer direction comes into contact with the guide surface to regulate the progress of the sheet-like article, and the sheet-like article is gradually shifted in the transfer direction. Wait until the overlapping state is resolved.

Furthermore, by raising the front of the support member, it is possible to more reliably feed each sheet of the sheet-like article from the sheet storage section.

Furthermore, by making the support member bulge at its feeding center, the sheet-like article is not supplied to the storage area in an inclined state when the sheet-like article is transported.

<Examples> The present invention will be specifically described below based on illustrated examples. Reference numeral 1 denotes a sheet-shaped article transfer device according to the present invention, and as shown in FIG. 1, this device is arranged so as to face a storage area S in a so-called main machine H for processing such as cutting and printing. use. Note that the side of the storage area S of the sheet-like article transfer device 1 is defined as the front, and the side opposite to the storage area S is defined as the rear. This sheet-like article transfer device 1 includes a support 3 for a machine frame 2, a lifting device 4 provided on one side of the support 3, a support member 5 provided on the other side, and a flow prevention device. body 6 as the main component. In addition, two casters 9 and four fixed wheels 10 are provided at the bottom of the machine frame 2, allowing the sheet-like article transfer device l to be moved freely as necessary when there are multiple punching lines or printing lines. is now possible. Incidentally, as shown in FIG. 1, the casters 9 may be driven by a motor M, or, of course, the sheet-like article transfer device 1 may be fixed for each line without providing the casters 9 and the fixed wheels 10. There is no harm in doing so.

Each precept element will be specifically set out below. First, pillar 3
As an example, two columns are provided perpendicularly to the machine frame 2, and the lifting device 4 is attached to a shaft 11 provided so as to connect the upper ends of these two columns 3. This elevating device 4 has a mast 13 whose upper end is rotatably provided with respect to a shaft 11, a sprocket 16 provided on the shaft 11, and a sub-keft 17 provided at the bottom of the mast 13. The forks 14 are respectively attached to two chains 18. The mast 13 is tilted around the shaft 11 by a cylinder 15 provided near its lower end so that the lower part of the mast 13 projects rearward.

Further, the fork 14 is a member on which a corrugated cardboard sheet D, which is an example of a sheet-like article, is placed.
It is for lifting. Incidentally, by lifting the corrugated cardboard sheet D by the lifting device 4, it becomes easier for the operator W to feed the corrugated cardboard sheet D to the side of the support member 5, as shown in FIG. Incidentally, the inclination of the mast 13 and the raising/lowering state of the fork 14 are set by switches So and St, respectively. In addition, on the floor surface on the lifting device 4 side of the support 3, there is a mounting roller R installed in a relatively long track shape.
are provided in three rows on the left, right and center. Incidentally, this placing roller R is for placing the corrugated cardboard sheets D, which are to be lifted up by the forks 14, in a stacked state and divided into several piles. Furthermore, rollers 19 are provided on the shaft 11 so as to sandwich the chain 18 therebetween. Incidentally, this roller 19 prevents the corrugated sheet D from coming into contact with the chain 18 when feeding the corrugated sheet D from the fork 14 side to the support member 5 side, and also allows the corrugated sheet D to be smoothly fed. Next, the support member 5 will be explained. This support member 5 includes, for example, a platform-like frame 20 and four rows of belt conveyors 21 layered in the transport direction. Each belt conveyor 21 includes a driven pulley 22 provided at the tip of the support member 5,

is wound with a moderate amount of tension applied. Moreover, between the driven boob IJ22 and the drive pulley 23,
A plurality of support rollers 27 are provided to support the strip belt 26 from below. Support roller 2 in this way
The surface formed on the upper part of the belt-shaped belt 26 supported by the belt 7 is defined as a transfer surface 27a. Further, the driving pulleys 23 of each belt conveyor 21 are provided on the same axis, and the input coupler 28 is also provided on this axis.
Output pulley 29 provided on the output shaft of motor M2, which is the drive source
A chain 30 is wound between. Incidentally, since the various pulleys and various belts have the above-described structures, the motor M2 is rotated by operating the switch S2, and thereby the belt-like belt 26 on the transfer surface 27a can be moved forward. Furthermore, as shown in FIG. 6, among the four belt conveyors 21, the conveyance surfaces 27a of the two intermediate belt conveyors 21 are made higher than those of the other belt conveyors 21 by a height h, so that the support member 5 can be fed. The center is formed into a raised shape. Incidentally, by adopting such a structure, when the corrugated cardboard sheet D in the middle of being transferred comes into contact with the transfer surface 27a of each belt conveyor 21, the central part of the corrugated cardboard sheet D is transferred with relatively strong pressure contact, The corrugated cardboard sheet D is not supplied to the storage area S in an inclined state. Also belt conveyor 21
A plurality of auxiliary rollers 31 are arranged on both sides and jRt2 is provided. Incidentally, the auxiliary rollers 31 are used to support the ends of the corrugated cardboard sheets D that tend to sag and assist in conveyance when the width of the corrugated cardboard sheets D is too large to be accommodated by the widths of the four belt conveyors 21. It is.

Although the auxiliary roller 31 is used in this embodiment, the belt conveyor 21 as described above may be applied to this portion. Next, as a characteristic configuration of the present invention, the transfer surface 2
A flow prevention body 6 is provided to the frame 20 so as to cross above the frame 7a. The outflow prevention body 6 has the following mounting structure in order to make its installation position variable. That is, rails 32 are provided on each side of the frame 20, and thereby the base of the support member for supporting the outflow prevention body 6 is supported slidably. A driven pulley 33 is provided on the front side of the rail 32, a drive booby IJ34 is provided near the motor M3 which is the drive source, and a turnboo IJ35 and a tension pulley 36 are provided between these two boobies. The twisted belt 37 is wound around the belt with an appropriate tension applied thereto. This conogdo belt 3
7, the installation position of the outflow prevention body 6 is shifted as described later. Further, the drive pulleys 34 provided on each side of the frame 20 are provided coaxially, and a chain is connected between the input turn 1738 provided on this shaft and the output pulley 39 provided on the output shaft of the motor M3 serving as the drive source. 40 is wound. Incidentally, with the above structure, the motor M3 rotates when the switch S3 is operated, and the Kongdo belt 37 is thereby moved to the driven boob 1J.
33 and turn pulley 35 so that it can move forward or backward. Reference numeral 41 denotes a mount plate on which the motor M3 is mounted, and its bottom part is bent at 90 degrees to form a mount part 42, and the mount plate 41 has an elongated notch 43 approximately in the center thereof. form. By the way, the mounting part 42 is the motor M3
This is where the chain 4 is mounted, and the notch 43 is where the chain 4 is mounted.

This is for fixing the mount plate 41 to the frame 20 at an appropriate position when the mount plate 41 is rotated back and forth.

The outflow prevention body 6 includes two sliding parts 45 that are provided so as to fit into each of the rails 32 provided on the frame 20, and two support arms that are rotatably attached to the sliding parts 45. 47, and a regulating body 48 rotatably attached to the tip of the support arm 47, and the sliding part 45 is connected to the cogged belt 37 between the driven pulley 33 and the turn pulley 35 at approximately the center thereof. Fixed. Incidentally, by adopting such a structure, as each cogged belt 37 moves back and forth between the driven pulley 33 and the turn pulley 35, the outflow prevention body 6 moves back and forth on the transfer surface 27a. Further, an adjustment bolt 46 is provided on the front side of the sliding portion 45. This adjustment port 46
The tip of the support arm 47 contacts the support arm 47, and the height of the contact position can be adjusted. Incidentally, by adopting such a structure, it is possible to set the initial height in a state where the corrugated board sheet ID is not flowing on the transfer surface 27a. Further, the regulating body 48 is a cylindrical member, and its side peripheral surface serves as a guide surface 49. Note that the upper part of the transfer surface 27a between the regulating body 48 and the support column 3 is
This is the part where the corrugated paperboard sheet D on top of the paperboard sheet D is transferred and placed, and this part is defined as the sheet storage part A. Incidentally, when the corrugated cardboard sheet D is transferred on the transfer surface 27a, as shown in an enlarged view in FIG.
Coupled with the transfer of the corrugated sheet D in contact with a, the upper end of the corrugated sheet 1-D in the transfer direction comes into contact with the guide surface 49 to restrict the transfer of the corrugated sheet D, and the corrugated sheet D is slightly The overlapping state is alleviated by waiting so as to be shifted in the transport direction.

Although the regulating body 48 is rotatable in this embodiment, it is also possible to fix the regulating body 48 to the support 47 and make it unrotatable, so that the corrugated cardboard sheet D is transported so as to rub against the guide surface 49. good. In addition to the cylindrical member, the regulating body 48 has a triangular prism whose negative side is a guide surface 49 as shown in FIG. 7(a), and the guide surface 49 and the transfer surface 2
It may be fixed and installed so that the angle with 7a is an acute angle, or it may be a flat plate shaped into an arc as shown in Figure 7(b), or a flat plate as shown in Figure 7(c). may be fixed as is so that the angle with the transfer surface 27a becomes an acute angle. In short, the regulating body 4 of the outflow prevention body 6 may be one having a smooth guide surface 49 so that the contact surface with the corrugated paperboard sheet D forms an acute angle with the transfer surface 27a. Furthermore, on one side of the frame 20, there is an abutment plate 50 in which the upper part of the flat plate member is bent slightly outward.
Throw. Incidentally, the contact plate 50 is
When transferring the upper tiered pole sheet D to the support member 5 side,
This is for neatly aligning the side edges of the corrugated paperboard sheets D by bringing them into contact with the contact plate 50. Next, a jasseau T-51 is provided below such a support member 5. This has a rod 52 in the form of a screw shaft, and the end of this rod 52 is attached to the frame 20 of the support member 5.
It is rotatably connected to the bottom of the and the loft 52
is combined with a shaft (not shown) having a male thread that is driven and rotated by a motor M4 which is a part of the jack 51, and the loft 52 is driven by the motor M4.
is expanded, and the support member 5 is brought into a forward-lifted state. still,
The operation of extending or shortening the rod 52 by driving the motor M4 is performed by a switch S4.

Further, when the support member 5 is in the forward-lifted state in this manner, the corrugated cardboard sheets D can be fed sheet by sheet from the sheet storage section A more reliably. Further, a workbench 53 having an appropriate height is provided to the machine frame 2, and stairs 54 are provided on both sides of the workbench 53.

Incidentally, on this workbench 53, the worker W places the corrugated sheet D on the fork 14 in the sheet storage part A of the support member 5.
This is for when transferring manually. Of course, the workbench 53 does not need to be fixed to the machine frame 2, and may be prepared as a separate member.

The sheet-like article transporting device 1 according to the present invention has the above-described structure, and the method of using this device will be explained below. First, by operating the switch S, the fork t4 is driven to lift the cardboard sheet D placed on the loading roller R and adjust it to a height that is easy for the worker W to work on. The height of the storage area S in the machine H is adjusted by operating the switch S4 so that the front is lifted up.Next, the worker W moves the cardboard sheet from the lifting device 4 side to the sheet storage section A side of the support member 5. An appropriate number of corrugated sheets D are stored in the sheet storage section A by manually transferring the sheets D.

If switch s2 is turned on in this state, motor M
2 rotates, and along with this, the belt-shaped belt 26 is driven so as to send the transfer surface 27 forward. As a result, the corrugated cardboard sheet D in contact with the transfer surface 27a is transferred to the belt-shaped belt 26.
Move as if being pulled by. Then, when the corrugated sheet D in contact with the moving surface 27H moves a little, the rear end of the corrugated sheet D directly above it comes into contact with the belt-like belt 26 and moves, causing it to shift little by little. It is sequentially sent to the straight area S (Ill. At this time, the corrugated sheet D moves by passing between the transport surface 27a and the regulating body 48, so the upward force of the corrugated pole sheet D lifting the regulating body 48, The regulating body 48 rises to a position where the downward force due to its own weight is just balanced.Furthermore, the guide surface 49 of the regulating body 48 raised in this way is covered with cardboard as shown in an enlarged view in FIG. The front end of the sheet D contacts and restricts the progress of the corrugated cardboard sheet D, and
The front end of the corrugated paperboard sheet D is gradually shifted along the guide surface 49 in the transport direction, and the overlapping state is eliminated. The corrugated cardboard sheets D sent out from the sheet storage section A in this manner are continuously supplied one by one to the storage area S in the book 1iH.

(Effect of the invention) In the present invention, a large number of laminated corrugated cardboard sheets D
Since the outflow prevention body 6 is provided on the side end face in the transport direction in contact with this, the corrugated cardboard sheet D has a large surface friction coefficient.
Even if it is, it can be smoothly supplied to the storage area S one by one.

Therefore, overlapping corrugated cardboard sheets D are not supplied to the storage area S, and troubles that occur during processing such as sheet-by-sheet cutting and printing performed in the book 111H can be avoided.

Further, the outflow prevention body 6, which is a characteristic component of the present invention, has a relatively simple structure in itself, is easy to manufacture, and can be easily attached to a conventional support member.
