Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an unpacking device for a package, and in detail,
This invention relates to an apparatus for cutting and winding wire rods used to bind papermaking pulp, waste paper, etc., and for removing the binding members of a package and unpacking it.

[Conventional technology]

Pulp, the raw material for papermaking, and collected cardboard boxes and waste paper are transported to paper mills, where they are compressed to improve transportation efficiency and make handling easier. It is concluded with. The cardboard and the like are put into a dissolving tank at a paper mill, but in order to prevent dissolution and stirring there, it is necessary to remove the binding member from the package in advance. The work to remove this binding member is done just before putting it into the melting tank.
It consists of cutting the binding members and collecting the binding members for separate disposal.

Conventionally, workers cut each binding member such as wire with a tool, resulting in extremely low work efficiency. Moreover, since the binding members spread around the package and fall, it takes time to pick them up. Moreover,
If the binding member bounces during cutting or collecting operations, there is a problem that requires constant attention during the operation.

By the way, Japanese Unexamined Patent Publication No. 60-68240 discloses a cutting device for cutting a binding member that binds packages such as books stacked horizontally, and a device for cutting dents by shifting the sides of the packages in the advancing and retreating direction of the cutting device. A binding cord cutting device is described that includes a giving member, a recess forming member facing the recess forming member, and a device for gripping the binding member with a recess formed on the side surface of the package.

[Problem to be solved by the invention]

According to the above structure, the cutting device can be advanced into the recess on one side to cut the binding member, and the binding member can be removed by retreating the gripping member. However, the gripping member that grips and pulls the binding member has to repeat the cutting and pulling operation for each binding member when there are many cut binding members, which is extremely inefficient. There are drawbacks.

It should be noted that the binding member is pressed so as to create a dent to make it easier to cut or grab, but the dent formed by this is not formed on the side of the package. However, there is a problem in that the binding member cannot be loosened directly, and the binding member stuck in the package cannot be easily removed.

The present invention has been made in order to solve the above-mentioned problems.The purpose of the present invention is to allow the unpacking work to be performed extremely quickly and to pack cut binding members into small pieces, so that the operator can To provide an unpacking device for a package that can mechanically unpack the package without having to work directly at the machine.

〔Example〕

The present invention will be explained in detail below based on examples.

Figure 1 is a front view of the device 1 for unpacking packages, which includes crushed cardboard boxes, compressed waste paper, etc.
Packing body 2 such as paper pulp stacked together
A package loading device 3 such as a roller conveyor for transporting the package, a cutting device 5 for cutting the binding member 4 such as wire or resin tape that ties around the package 2 as shown in FIG. A winding device 6 for winding up the member 4 and a pressing device 7 are provided. It should be noted that the package 2 is bundled in order to increase the transportation efficiency during truck transportation and to make it easy to handle.

The above-mentioned cutting device 5 and winding device 6 are attached to the tip portions of a cutting arm 8 and a winding arm 9, respectively, and both arms 8 and 9 are located above the package loading device 3 in the unpacking position. A support frame 10 provided in
It is attached to the package body 2 and is rotatable in directions facing each other toward the sides of the package body 2. Therefore,
hydraulic cylinders 12 each having a rotating base attached to a bracket 11 depending from a support frame 10;
13 allows the cutting device 5 and the winding device 6 to approach and separate from the side surface of the package 2 simultaneously or independently. In order to facilitate unpacking operations such as cutting and winding the binding member 4 using such devices 5 and 6, the package 2 is placed on the roller conveyor 3 with the binding member 4 being vertical. Ru.

The cutting device 5 cuts the package 2 as shown in FIG.
two cutting arms 8 provided in the conveyance direction;
8, with a sharp cutter 5a at its tip.
is attached toward the package 2. The cutter 5a is horizontally long so that it can cut the binding member 4 wound around several left and right parts of the package 2 at once. In addition,
The cutting arms 8 are connected to each other by connecting rods 8 shown in FIG.
a, which allows the two cutting arms 8 to behave in the same way and increases the rigidity of the arms.

The winding device 6, as shown in FIG. It is possible to insert the body contact members 15, 15 and move back and forth to the left and right, as well as rotate. The package contacting member 15 is a guide ring, and as shown in FIG. 4, it is attached to the tip of the winding arm 9 at a position on substantially the same horizontal plane, facing the cutting device 5.
They are arranged at intervals on a straight line extending in the horizontal direction along the side surface of the package 2. This is Katsuta 5
It also functions to receive the reaction force when cutting the binding member 4 by a.

As shown in FIG. 5, the fork-shaped claw body 14 is
The claw 14a or 14b connects the package 2 and the binding member 4.
When the fork-shaped pawl body 10 is rotated by a hydraulic motor 16, the binding member 4 wound around several places is wound up at once by the rotational force. For this purpose, the two or more claws are, for example, rods with a pointed tip and a semicircular cross section. As shown in FIG.
A is attached to the hydraulic motor 16 and the pronged claw body 1.
4 and is integrally movable in the transport direction of the package 2.

The winding arm 9A has a slightly wider end as shown in FIG.
A hydraulic motor 16 is mounted on the side surface of a slider 19 that slides in the upper and lower grooves. Note that the two winding arms 9 are also integrated by a connecting rod 9a (see FIG. 1).

On the backs of the guide rings 15, 15, as shown in FIG. 6, the fork-like claws 14 are attached along the sides of the package to the package abutting members 15, 15 (see FIG. 1).
A hydraulic cylinder 20 that moves horizontally forward and backward is attached so as to be inserted therethrough, and the fork-shaped pawl body 14 advances to one side of the package 2 by its contraction operation. A semi-circular cover 21 is integrated with the slider 18, and the tip of a piston rod 20a of a hydraulic cylinder 20 is connected to the back of the cover 21. The cover 21 is deep at the attachment point of the slider 19, but as shown in FIG. One nail is exposed. This is to prevent the cover 21 from interfering with the packaging body 2 and to prevent it from interfering with insertion into the binding member 4 when the pronged claw body 14 advances to one side of the packaging body 2 together with the cover 21. be. The cover 21 not only transmits the expansion and contraction operation of the hydraulic cylinder 20 to the fork-like claw body 14, but also serves as a guide when the fork-like claw body 14 rotates and winds up the binding member 4. Note that the cover 21 is shorter than the fork-shaped claw body 14 as shown in FIG.
When inserting the tip of the guide ring 15a into the guide ring 15a, there is no interference.

In addition to the above-mentioned devices, a pressing device 7 for pressing the package 2 downward is provided, which is suspended from the support frame 10 shown in FIG. Hydraulic cylinder 23 rested with fixed stop plate 22
, a pressing pad 24 attached to its tip to press the top surface of the package 2, and a fork-shaped comb member 25 extending downward at its side end. The pressing pad 24 is used to loosen the binding member 4 binding the package 2 by compressing it slightly on the winding device 6 side, thereby facilitating the insertion of the claw 14a or 14b. Note that the pressing position by the pressing pad 24 is the winding device 6.
Although it is preferable to compress the package 2 and weaken the tension of the binding member 4, the pressing point may be anywhere on the top surface. When winding up the cut binding member 4 with the winding device 6, the comb member 25 pulls the binding member 4 which has become stuck in the corner of the package and has become difficult to slip before winding up.
This is to prevent the upper part of the stacked pulp from shifting due to its tensile force. By the way,
Hydraulic motor 16 and hydraulic cylinders 12, 13, 2
Actuators such as 0 and 23 operate automatically by controlling the opening and closing of electromagnetic switching valves, etc.
The start and stop of the operation is performed by switching the opening and closing of each electromagnetic switching valve by detecting that a movable part has reached a predetermined position using a limit switch, a pressure switch, etc. (not shown).

Incidentally, among the guide rings 15 described above, the ring 15b on the winding arm 9A side has a forked claw body 1.
A removal member 26 is built in to remove the wound binding member 4 from the pronged claw body 14 when the binding member 4 is moved backward. As shown in FIGS. 9a and 9b, this removal member 26 is, for example, a rotating ring equipped with a passing portion 26a, and a claw 14 is provided in a space 27 next to the passing portion 26a.
a, 14b are inserted. As shown in FIG. 10, the guide ring 15b has a groove that allows the rotary ring 26 to rotate but prevents it from moving in the left and right direction. Therefore, when the fork-like claw body 14 rotates, it rotates together, and when the fork-like claw body 14 advances or retreats, the binding member 4 wrapped around the fork-like claw body 14 is squeezed by the peripheral portion 26b and the transition portion 26a. It is now possible to drop it.

According to the configuration described above, the binding member 4 of the package 2 can be cut and wound up by operating as follows. The package 2 that has been transported by a truck or the like is placed on the roller conveyor 3 while being bound by a binding member 4. At that time, the package 2
is in a posture such that the binding member 4 is vertical. As shown in FIG. 11a, the cutting arm 8 and the winding arm 9 are rotated outward, and the cutting device 5, the winding device 6, and the pressing device 7 are retracted. When the package 2 reaches the packing position, the limit switch is activated, the roller conveyor 3 is stopped, and the hydraulic cylinder 13 shown in FIG.
is rotated in two directions of the package. The forked claw body 14 is in a state of being retracted to the side [see FIG. 11b], and the winding device 6 attached to the winding arm 9
The two guide rings 15 that make up the package 2
(See Figure 12). The rotation of the take-up arm 9 is stopped due to the operation of the pressure switch, etc., and the hydraulic cylinder 12 shown in FIG.
The binding member 4 is cut at the other side of the package 2 whose movement is prevented at step 5 (see FIG. 13).

In this state, the pressing device 7 descends and presses the pressing pad 2.
4, the winding device 6 side of the package 2 is compressed [first
See Figure 4a]. The volume of the package 2 becomes partially small, and the binding member 4 becomes loose, causing the binding member 4 and the package 2 to become loose.
A gap for inserting one claw of the pronged claw body 14 is secured between the two. Therefore, the first winding device 6
When the hydraulic cylinder 20 shown in the figure is contracted, the prongs 14 are inserted into the binding member 4 [Fig. 14b
reference〕. When advancing, the elongated fork-like claw body 14 passes through the guide rings 15, 15, so that the horizontal posture of the fork-like claw body 14 is stably maintained.

Next, the pressing device 7 is slightly raised above the package 2, but the comb member 25 is still in a position facing the upper end of the package 2 (see FIG. 15). The hydraulic cylinders 12, 13 are extended and the cutting arm 8 and the winding arm 9 are pivoted outward. The pronged claw body 14 pulls the cut binding member 4 and makes it easier to move the binding member 4 biting into the corner of the package 2.
At this time, the comb member 25 prevents the upper part of the package 2 from shifting or collapsing (see FIG. 16a). The hydraulic motor 16 is rotated (see FIG. 16b), and the binding member 4 springs up from the cover 21 as shown in FIG.
As shown in FIG. 19, the binding member 4 is wound up around the fork-shaped claw body 14 while being held down by the handlebars. Guide ring 15,1
Since the pronged claw body 14 is held at 5, the claw 14
A, 14b are prevented from bending or deforming.

The pressing device 7 is further raised, and at this time the fork-shaped claw body 14 is retracted by the extension of the hydraulic cylinder 20 (see FIG. 17b). The rolled-up lump of the binding member 4 wound up during the movement is transferred to the guide ring 15b.
It is squeezed out by the inner rotating ring 26 and dropped into the storage box 28 shown in FIG. 1 [FIG. 17a
reference〕. If the binding member 4 is tied in other directions as well, the swivel base 29 below the roller conveyor 3 is rotated (see FIGS. 18a and 18b). The binding member 4 is cut, rolled up, and removed in the same manner as described above, and the unpacked package 2 is returned to its original orientation and transported by the roller conveyor 3. Note that instead of the structure in which the roller conveyor 3 is rotated, the cutting arm 8 and the winding arm 9 may be rotated with respect to the support frame 10. Of course, if the binding members 4 are not wound so as to intersect, it goes without saying that the turning mechanism is not necessary.

In the example described above, the package 2 is pressed by the pressing device 7.
If the fork-like claw body 14 can be inserted into the binding member 4 without being compressed by the pressing device 7, the pressing device 7 may not be provided. Further, if the binding member 4 is not strongly bitten into the package 2 and the binding member 4 can be wound up by the rotation of the prongs 14, there is no need to prevent the comb member 25 from slipping.
There is no need to rotate the winding arm 9 outward before winding. Depending on the quality and properties of the package 2 and the degree of binding by the binding member, it may be selected and operated as appropriate, and it may be determined whether or not to be employed in the unpacking device. Further, instead of the roller conveyor 3, a stationary package mounting device such as a mounting table or a workbench (not shown) on which the package 2 is placed under the support frame 10 may be used. Incidentally, it is not necessary to cut the binding member 4 before inserting the pronged claw body 14 into the binding member 4. Forked claw body 14 with or without the pressing device 7
As long as it can be inserted into the binding member 4 in the binding state, the operations may be performed in a different order from the above description.

According to the above-mentioned operation, the binding members that bind the packages are wound up around the fork-like claws, and are gathered into small pieces with low bulk. Moreover, the cutting device, the winding device, and the pressing device are retracted, so that the arrival of the package and the unpacking of the unpacked items are not hindered, and the unpacking operation can proceed smoothly. Moreover, even if the worker does not work directly in front of the package, the package can be unpacked continuously mechanically, ensuring worker safety and improving work efficiency.
