Abstract

PURPOSE:To reduce time taken for accumulating sheet materials by providing a sheet bundle holding means for pressing from above the accumulated sheet materials in a position spaced inward from an end of said material. CONSTITUTION:A sheet holding means 6 is provided which is constituted to support a holding member 11 on an end of a piston rod 7a in an air cylinder 7 through a shock absorbing springs 12, 13. Thus, until sheet materials as a sheet bundle are lifted by a sheet bundle lifting member 28 and sandwiched by a sheet bundle sandwiching means 32, the sheet materials are pressed by the sheet holding means 6 so that the sheet materials are sandwiched by said means 32 as an orderly sheet bundle without any disorder. Thus, since a predetermined number of sheet materials does not need to be beforehand bundled by tape or the like, time taken for accumulating the sheet materials can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet bundle separation and supply device that takes out a predetermined number of sheet materials as a sheet bundle from a stack of sheet materials.

Sheet materials such as paper and thin metal plates are often formed by cutting strips to a predetermined length, and then stacking them in large numbers for the next process such as removal and packaging. . After forming such a stack of sheet materials, when packaging is to be performed next time, a predetermined number of sheet materials (for example, the number of sheets per packaging unit for packaging) are collected from the stack into a sheet bundle. It is necessary to take it out.

Conventionally, as a device for taking out a predetermined number of sheet materials from a sheet stack as a sheet bundle as described above,
A pusher pushes out a predetermined number of sheets at the top of the sheet stack in a substantially horizontal direction, and the pushed-out sheet bundle is placed on a conveying means such as a roller conveyor and sealed.
・Those that separate from aggregates are known. However, in such a sheet bundle separation and supply device using a pusher, the sheet materials are separated in advance into a predetermined number so that the predetermined number of sheets 1 constituting the sheet bundle are not disturbed when being pushed out by the pusher. It was necessary to bundle and accumulate each number of sheets using tape or the like. Naturally, bundling the sheet materials when accumulating them in this way requires a considerable amount of manpower and equipment.
It also increases the time required for sheet material accumulation.

The present invention has been made in view of the above circumstances, and it is possible to take out a predetermined number of sheet materials as a bundle from a sheet stack in which the sheet materials are simply piled up one by one. It is an object of the present invention to provide a sheet bundle separation and supply device that makes it unnecessary to bundle sheet materials into predetermined number of sheets when accumulating the materials.

The sheet bundle separation and supply device of the present invention includes a sheet bundle pressing means for pressing down the stack from above at a position inwardly away from one end of the sheet materials stacked one by one to form the stack; a sheet level detection means for detecting the position of a predetermined number of sheet materials from the top in the body; and a sheet level detection means disposed at a position facing one end of the sheet materials, and an intervention position that intervenes in the stack and an exit position away from the stack. a sheet bundle lifting member formed to be movable in a substantially horizontal direction between the ends and also in a vertical direction; A movable sheet bundle supporting means, when the sheet bundle lifting member is in an exit position, faces a gap between a predetermined number of sheets detected by the sheet level detecting means and a sheet below it. A lifting member driving device that, after being set in the vertical position, sends it in a substantially horizontal direction to an intervention position, raises it to a predetermined height at the intervention position, and then lowers it to a position where the next predetermined number of materials to be sorted is pressed from above. , the sheet bundle holding means is moved to a position where it can grip the one end of the sheet bundle made up of a predetermined number of sheet materials lifted by the sheet bundle lifting member, and the sheet bundle holding means grips the sorted bundle. a clamping means driving device that later moves the sheet bundle supporting means in a substantially horizontal direction to separate the sheet bundle from the upper part of the stack; It consists of a sheet bundle pressing means control device that sets the sheet bundle pressing means to the stacked body suppressing position.

In the sheet bundle separation and supply device of the present invention having the above configuration, a predetermined number of sheet materials on the upper part of the collector are lifted as a sheet bundle by the sheet bundle lifting member and are held by the sheet bundle supporting means. Since the sheet material is pressed by the sheet bundle holding means, the sheet material is not disturbed and is held by the sheet bundle supporting means as an orderly bundle of sheets. Therefore, unlike when using the above-mentioned device using a pusher, it is not necessary to bundle the required number of sheets in advance with tape or the like.

It has chuckers 33 and 34 which are opposed from above and are moved vertically relative to the claw members 30a and 31a by a drive device (not shown). The sheet bundle holding means 32 is moved in each of the above directions (directions of arrows D and B) by a holding means driving device 35 constituted by a known device such as an air cylinder device.

A sheet bundle auxiliary lifting member 36 is disposed at a position facing the corner of the web 1 on the side of the sheet stacking upper member 28. As shown in detail in FIG. 2, this auxiliary lifting member 36 has a substantially L-shaped shape with a tip facing toward the center of the web 1, and is attached to the front end of a base 38 to which a handle 37 is fixed to the side. The edge portion 39 is fixed, a piston rod 40a of a vertically moving cylinder 4o is fixed to the upper part of the base 38, and a forward cylinder 41 and a backward cylinder 42 are arranged behind the base 38. The above three cylinders 40, 41, 42
is composed of, for example, an air cylinder, etc., and the forward cylinder 41 is arranged at a position where the contact portion 4lb fixed to the tip of the piston rod 41a can come into contact with the rear end surface 38a of the base 38, and the backward cylinder 42 is arranged at a position where the contact portion 4lb fixed to the tip of the piston rod 41a can come into contact with the rear end surface 38a of the base 38. The piston rod 42a is passed through the through hole 38b provided in the base 38, and when the piston rod 42a is contracted, the abutment part 42b fixed to the tip of the piston rod 42a is inserted into the base 38.
is designed to be pulled backwards (to the right in Figure 1). A pressurized air pipe 43 connected to, for example, an air compressor is housed in the -f edge part 39, and the pipe 43 has a tip that applies pressure from the tip of the edge part 39 to the center of the web 1. A nozzle 44 that blows out air is connected.

Further, the front edge portion of the edge portion 39 is formed into a curved surface in which the upper surface gently approaches the lower surface.

The operation of the apparatus of this embodiment having the above configuration will be explained below. When separating the wafers 1 stacked on the pallet 2 by a known method into a bundle of a predetermined number of packaging units from the stack 3, first the pallet 2 on which the stack 3 is placed is placed in the position shown in FIG. Set. Next, air cylinder 7
The pressurized air control device 45 that controls the pressurized air supply to the presser member 11 is activated, and the air cylinder 7
The piston rod 7a is extended. As a result, the presser member 11 supported by the piston rod 7a moves the stack 3 at a position inwardly away from one end 1a of the web 1.
Press down from above. At this time, the rubber 14 fixed to the lower surface of the presser member 11 and the spring 1'2.
This action prevents a large impact from acting on the web 1 through the padding cardboard 5, and prevents damage to the web 1 or the padding cardboard 5.

Next, the operator moves the corner of the woven web 1 of the highest packaging unit number of the stack 3 (the corner facing the auxiliary lifting member 36) into a bundle of woven web 4 along with the upper and lower padding cardboard 5.
The web 1 is grasped as such, and is lifted up from the web 1 below it. When the web bundle 4 is lifted up, the auxiliary lifting member 36 is moved forward by the operator grasping and operating the handle 37, so that the front end of the edge portion 39 of the auxiliary lifting member 36 touches the web bundle 4. inserted below. Next, by an operation such as operation 40, the forward cylinder 41 is actuated to extend the piston rod 41a, and the auxiliary lifting member 36 is pushed by the piston rod 41a, causing the edge portion 39 to deeply penetrate into the stack 3. move forward until

When the edge part 39 is inserted into the stack 3 in this way, air is ejected from the nozzle 44 provided on the edge part 39, and this air causes the paperboard 5 or the web above and below the edge part 39 to be blown out. 1 are spread upward and downward, and the edge portion 39 can be easily inserted into the stack 3 without being hindered by the cardboard 5 or the web 1.

The forward cylinder 41 is deactivated when its piston rod 41.8 is extended by a predetermined length, and then the vertical movement cylinder 40 is activated to retract its piston rod 40a. As a result, the auxiliary lifting member 36 is raised, and the web bundle 4 is further lifted up by the edge portion 39 of the auxiliary lifting member 36 (the state shown in FIG. 1). When the web bundle 4 is lifted in this way, the lower surface of the web bundle 4 (directly, the lower surface of the support pole paper 5) touches the edge portion 3.
However, since the front edge of this edge portion 39 is formed into a curved surface as described above, the web bundle 4
This edge portion 39 prevents the web 1 or the cardboard 5 from being folded or damaged.

When the web bundle 4 is lifted as described above, the arm 18 of the sheet level detecting means 15, which is in contact with the roller 23 through the cardboard 5, swings. The air cylinder 22 is connected to the arm 18 by the photoelectric device described above.
The operation of the air cylinder 22 is controlled so that it assumes a predetermined swing position, and the air cylinder 22 is stopped at that position. When the arm 18 is set at a predetermined swing position in this way, the amount of protrusion of the piston rod 22a of the air cylinder 22 is detected by the rond length detecting device 27, so that the amount of protrusion of the piston rod 22a of the air cylinder 22 is detected. Surface level is detected. Since the thickness of the web bundle 4 consisting of a predetermined packaging unit number of webs 1 and two sheets of padding cardboard 5 is constant, if the upper surface level of the upper padding cardboard 5 is detected as described above, ,
The lower surface level of the support pole paper 5 below the web bundle 4 is detected.

The lifting member drive device 29 moves the sheet bundle lifting member 28 in the exit position away from the stack 3 in response to a signal S representing the lower surface level of the backing cardboard 5 on the lower side of the web bundle 4. The sheet bundle lifting member 28 is driven in the vertical direction to set the sheet bundle lifting member 28 at a vertical position opposite to the gap below the lifted web bundle 4. Next, the lifting member driving device 29 moves the sheet bundle lifting member 28 set in this vertical position forward in a substantially horizontal direction, and stacks the front end of the sheet bundle lifting member 28 on the lower side of the web bundle 4. Intervene within the body 3. At this time, as mentioned above, the stack 3 is pressed from above by the sheet bundle presser 6, so even if the web bundle 4 comes into contact with the advancing sheet stack lifting member 28, it will not shift on the stack 3. There is no need to worry.

Note that when the sheet bundle lifting member 28 is interposed below the web bundle 4 as described above, for example, using a link mechanism or the like, the sheet bundle lifting member 28 that is closer to the second member 36 that lifts the web bundle 4 is moved. If the side end of the upper member 28 is intervened first and the opposite side end is intervened later, the sheet bundle lifting member 28 can intervene into the stack 3 more smoothly.

When the sheet bundle lifting member 28 intervenes below the web bundle 4, the lifting member drive device 29 next
8 by a predetermined length. As a result, the portion on the one end la side of the web 1 constituting the web bundle 4 is largely lifted from the web 1 below by the sheet bundle lifting member 28. Note that when the sheet bundle lifting member 28 lifts the web bundle 4 in this way, the webs 1 constituting the web bundle 4
is curved so that the upper part is concave, but as mentioned above, the end surface 14a of the rubber 14 of the presser member 11 is formed into a convex curved surface, so the backing cardboard 5 or the web 1 may be bent or damaged. This will be prevented.

When the web bundle 4 is lifted by the sheet bundle lifting member 28, the supporting means drive 35 is then actuated, and the sheet bundle clamping means 32 moves from its upper standby position to the pawl members 30a, 31 . a and chutka 33
．． 34 is lowered to a position opposite to one end of the web bundle 4 (note that the vertical position of the web bundle 4 being lifted is determined by the vertical position of the sheet bundle lifting member 28, By setting the sheet bundle holding means 32 at a predetermined vertical position with respect to the sheet bundle lifting member 28, the sheet bundle holding means 32 can be accurately set at the above position. Thereafter, the sheet bundle holding means 32 is advanced in a substantially horizontal direction to a position where the web bundle 4 enters the gap, and is stopped at that position. Next, the chuckers 33 and 34 of the sheet bundle holding means 32 are moved downward, and one end of the web bundle 4 is held between the chuckers 33 and 34 and the claw members 30a and 31.
It is held between a. When the sheet bundle holding step 32 is lowered to hold the web bundle 4 in this manner, the lower portions of the fingers 30. Therefore, the downward movement of the sheet bundle holding means 32 is not hindered by the sheet bundle lifting member 28.

As mentioned above, one end of the web bundle 4 is connected to the chucker 33.34.
and the claw members 30a and 31a, the air cylinder 7 of the 1,000-stage sheet bundle presser 6 is operated to compress the piston rod 7a, and the presser member 11
The suppression of the aggregate 3 due to this is released. Even when the pressure on the stack 3 by the pressing member 11 is released, the web bundle 4 is already held by the sheet bundle holding means 32 as described above, so the webs 1 constituting the web bundle 4 become disordered. There's nothing to do. Next, the sheet bundle lifting member 28
The web 1 is swung in the downward direction of the arrow C in the figure, and its front end forms the stack 3 below the web bundle 4.
suppress from above. When the web 1 below the web bundle 4 is suppressed and fixed in this way, the web bundle 4
The sheet bundle holding means 32 supporting the web bundle is moved rearward, that is, to the right in FIG. Move 4. Therefore, the sheet bundle supporting means 3
The chuckers 33 and 34 of No. 2 are moved upward to release the web bundle 4, and the web bundle 4 separated from the stack 3 is transferred to the conveyance means, which carries it to the next packaging process. Supplied.

In the embodiment described above, the sheet bundle lifting member 28
An auxiliary lifting member 36 is used to slightly lift the web bundle 4 before the web bundle 4 is intervened under the web bundle 4, thereby facilitating the intervention of the sheet bundle lifting member 28. There is no special auxiliary lifting member 36 such as
The sheet bundle lifting member 28 may be easily inserted into the stack 3 by lifting the sheet bundle lifting member 28 to a certain level.

Further, in the above embodiment, in order to protect the upper and lower parts of the wafer bundle 4 that is separated from the stack 3, a padding cardboard 5 is arranged for each predetermined number of wafers 1.
The sheet bundle separation and supply device of the present invention can of course be applied to a stack of sheet 1 in which no padding cardboard is arranged.

Furthermore, as a device for detecting the position of a predetermined number of sheet materials from the top in the stack, a known device other than the sheet level detecting means 15 in the above embodiment may be used, but the sheet level detecting means 15 is The roller shaft may 17 arm 1
By changing the length of the protrusion from 8, it is convenient because the thickness of the sheet bundle can be easily changed.

As explained in detail above, according to the sheet bundle separation and supply device of the present invention, there is no need to bundle the sheet materials into a predetermined number of sheets using tape or the like, and the sheet materials are neatly separated from the sheet collection body by a predetermined number. Since it is possible to shift the sheet materials, the manpower and cost required to bundle the sheet materials can be eliminated, and the time required for stacking the sheet materials can be shortened.
