Abstract

PURPOSE:To correspond to one stacking spot at each type of a platelike body by supporting the platelike body temporarily in advancing a pair of center holding bars ahead when the conveyed platelike body has come to fullness on a lifting table, and carrying out this lifting table in the interim. CONSTITUTION:A platelike body 3 so far conveyed by a conveyor 1a is dropped on a lifting table 4a and sligned by guide plates 7a, 7b. This pltelike body 3 is reached to the specified quantity in pile, a center holding bar 5a at the downstream is projected onto the table 4b, and another center holding bar 5a at the upstream is projected likewise later as long as the specified time. Afterward, while the platelike body 3 is held temporarily by these center holding bard 5a, 5b, the lifting table 4a is replaced with an empty lifting table. When platelike bodies 3' different in size each are conveyed, a conveyor 8 is lowered, making these conveyors 1a, 8, 1b be flush with one another, and these platelike bodies 3' are stacked on another lifting table 4b. A series of the same equipment is combinedly installed and made into multiply- connection. With this constitution, one stacking spot is made to correspond to one type platelike body, so that a floor space is reduced and, what is more, selection of the platelike body is much promoted into efficiency.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for depositing plate-shaped bodies such as plywood, fiberboard, metal plates, synthetic resin plates, etc., by sequentially loading them onto a lifting table at a deposition location. The present invention relates to a holding device for plate-like bodies in an input-type depositing machine, which is a means for carrying out stacked plate-like bodies.

[Conventional technology]

A conventional type of depositing machine for plate-like materials is, for example,
A conventional device disclosed in No. 5-4012, a device for stacking board materials such as paperboard, plywood, etc., which alternately switches between the front and rear stacking locations in the conveyance direction and transports the stacked plates from the stacking location to the outside of the machine. There is.

(Problems to be Solved by the Invention) The above-mentioned conventional device, as a means for carrying out the piled plate-like bodies,
By forming two sets of depositing locations at the front and rear in the conveyance direction and switching the stacking operation alternately, the plate-shaped bodies deposited during the pause are carried out from the depositing locations to the outside of the machine. Because of this, multiple deposition sites are required to deposit one type of plate-like material, and the deposition work that also serves as the sorting work for many types of plate-like materials requires a long deposition site, extremely multiple locations, and expensive facilities. It required the equipment of a depositing machine, which was unsatisfactory both functionally and economically.

In order to eliminate the above-mentioned drawbacks of the conventional apparatus, the present invention is capable of handling one type of plate-shaped body at one deposition location, allows the stacked plate-shaped bodies to be carried out of the machine at any time, and has a multi-layer structure. The object of the present invention is to provide a so-called multi-functional continuous feeding type sorting and stacking machine with a holding device for plate-shaped bodies, which can perform the sorting and stacking of many types of plate-shaped bodies at high speed and continuously.

[Means to solve the problem]

In order to achieve the above object, the apparatus of the present invention uses a conveyor and pinch rolls installed above the end of the conveyor to pinch and convey plate-like objects, and sequentially throw them onto an elevating table at a predetermined stacking location to deposit the plate-like objects. In a body-feeding type stacker, a front and rear set of middle supports are located slightly above the stacking level of the plate-shaped bodies deposited at the stacking location, and are installed at the front and rear of the stacking location in the transport direction, respectively, so as to be freely accessible. It consists of a cough holding bar and a control circuit that causes the rear side of the cough holding bar to protrude with a slight delay from the front side of the carrying direction. The body is temporarily held there, and when the empty elevating table rises after the carrying out work, the middle holding bar is released all at once, and the body is temporarily received on the middle holding bar. It is constructed so that the plate-like stopper is dropped onto the lifting table and the normal stacking operation is resumed.

Further, a fixed guide plate is disposed at the front in the conveyance direction on the side of the plate-shaped body, and a movable guide plate is disposed at the rear of the plate-shaped body in the conveyance direction. It is configured so that the front and rear sides of the plate-shaped bodies that are brought in and thrown in are aligned in the conveying direction by the pressing action, and are deposited in an orderly manner on the lifting table.

Furthermore, the conveyors installed at the front and rear in the conveyance direction above the plate-shaped body deposition area are individually separated and connected to each other by opening and closing vibrating conveyors whose tips are directed in the opposite direction to the conveyance direction. By freely constructing the structure,
The structure is such that it is possible to perform the sorting and stacking work of many types of plate-like bodies using a multiple structure.

[For production]

Since the device of the present invention is configured as described above, the third A
As shown in FIGS. 3D to 3D, the intermediate holding bar 5a is opened to the outside of the deposition location during normal deposition operation (FIG. 3A).

5b is a plate-shaped body 3a which has been deposited and is full.

3b to the outside of the machine, first, only the intermediate holding bar 5b on the front side in the conveying direction is projected into the depositing place during the interval between the stacking operations (FIG. 3B).

Next, the rear side in the conveyance direction of the plate-like object 3 in the falling process lands, a little later than the operation of the intermediate holding bar 5b on the front side in the conveyance direction, and the remaining rear side in the conveyance direction after a delay of about 0.3 seconds. The intermediate holding bar 5a is projected into the depositing place. The front side of the plate-like body 3 in the conveyance direction is temporarily received on the middle holding bar 5b on the front side in the conveyance direction (FIG. 3C). Next, if the plate-shaped bodies 3 continue to be thrown in, they will be received one after another on the intermediate holding bars 58, 5b, so that the plate-shaped bodies 3a, 3 that have been fully piled up during this time will be
Push out b from the lifting table and carry it out of the machine (3rd
(Fig. D) Although not shown, once the plate-like bodies 3a and 3b that have been fully deposited on the lift table are removed from the machine, the lift table at the deposition location is returned to the highest level, so the return After waiting, the intermediate holding bars 5a and 5b are opened all at once, and the plate-shaped body 3, which is a temporary receiver, is dropped onto the lifting table onto the intermediate holding bars 5a and 5b, and the normal stacking operation is continued. Therefore, when using the apparatus of the present invention, the conveyance operation of the plate-shaped bodies during the carrying-in process by the conveyor is replaced by the operation of carrying out the fully piled plate-shaped bodies to the outside of the machine. Therefore, there is no need to temporarily stop the operation, and as described above, the intermediate holding bars 5a and 5b are set in a time-limited manner so that the rear side in the conveyance direction is slightly delayed from the front side in the conveyance direction and protrudes into the depositing place. Because of this control, an unexpected situation in which the plate-shaped body 3 just before landing collides with the intermediate holding bar 5a on the rear side in the conveyance direction can be safely avoided.

(Example) Fig. 1 and Fig. 2 show an example of the implementation of the apparatus of the present invention, and show a conveyor 1a connected to a pre-stage process, for example, a sorting process, or a stacking system configured in multiple series. The conveyor 'la,
Pinch rolls 2a and 2b are installed above the ends of the 'lb's so that they can be held and conveyed freely, thereby configuring a feeding type plate stacking machine.

The deposition level of the deposition machine is maintained at a constant position by installing a level controller such as a photoelectric switch on the side (not shown) and controlling the elevation and descent of the lifting tables 4a and 4b. Therefore, a pair of front and rear intermediate holding bars 5a and 5b are installed slightly above the accumulation level, usually about a dozen or so above, so that they can move in and out in the front and rear directions in the conveyance direction, respectively.

The middle holding bars 5a, 5b hold the square timber etc. with roller devices 9a, 9.
The plate-shaped body 3 is supported by b and is constructed so as to be able to move in and out of the depositing place using an air cylinder 108 10b etc. and is in the process of being loaded.
It is configured so that it can be temporarily held, so-called. Further, the middle holding bars 5a and 5b are designed so that the rear side in the conveying direction can be made to protrude slightly after the time required for landing, for example, about 0.3 seconds, from the front side in the conveying direction. , 5b air cylinder 'lQa, 10
A timer or the like with different time limits is inserted into the control circuit 6 for activating the conveyor 1a or the conveyor 1.
A time limit is assigned to each of the detection signals of the plate-shaped object 3 detected by the photoelectric switch 11 etc. on b, and the activation timing is determined by setting the activation time to the intermediate holding bar 5b on the forward side in the conveying direction and the intermediate holding bar 5b on the rear side in the conveying direction. By delaying the bar 5a for a required period of time, it is possible to safely avoid a collision between the intermediate holding bar 5a and the plate-shaped body 3 on the verge of landing.

Next, in the apparatus of the present invention, a fixed guide plate 7a is disposed at the front in the conveyance direction on the side of the deposition place, and a movable guide plate 7b is disposed at the rear in the conveyance direction. A reciprocating "operation mechanism" such as No. 12 is attached, which is activated each time the plate-like material 3 is introduced, or every appropriate number of times the plate-like material 3 is introduced, to align the stacked state in the front and rear directions in the conveying direction by a pressing action, and a separate device is used. fixed guide plate 13a
, 13b, an air cylinder 14, and the like, movable guide plates 15a and 15b are configured to allow alignment of the left and right stacking positions. Furthermore, the apparatus of the present invention is capable of separating and connecting the conveyors 1a and 1b, which are respectively installed at the front and the rear in the conveyance direction above the depositing place.
A vibrating conveyor 8 whose tip is directed in the opposite direction to the conveying direction is constructed so as to be openable and closable by an air cylinder 15 or the like.
The structure is such that the deposition location can be arbitrarily changed by a sorting signal transmitted in the sorting process or the like.

(Effects of the Invention) The apparatus of the present invention is constructed as described above, and can handle one type of plate-shaped body at one depositing location, and can carry out the stacked plate-shaped bodies out of the machine at any time. Moreover, because it is a continuous feeding type sorting and stacking machine equipped with a so-called multi-functional plate holding device, it can perform the sorting and stacking of many types of plate-like objects at high speed and continuously due to its multi-unit configuration. The problem was that multiple deposition sites were required to deposit one type of plate-like material, and the deposition work that also had the task of sorting out many types of plate-like materials required a long deposition site and extremely multiple locations. This system completely eliminates the drawbacks of requiring expensive stacking machine equipment, which was unsatisfactory in terms of functionality and performance, and is especially powerful for sorting and stacking a wide variety of plate-shaped objects. This is a result of achieving this goal.
