FIG. 3 is a plan view showing a receiving elevator in the stacking hopper, FIG. 4 is a front view showing the receiving elevator in the stacking hopper, and FIG. 5 is stacking in the stacking hopper. It is the side view which looked at the discharge | emission means which sends out the integrated unit to the packaging means from the conveyance path side.
An integrated packaging machine 1 shown in FIG. 1 is an integrated unit in which a plurality of, for example, 10 sheets of substantially rectangular plate-like cases (hereinafter simply referred to as cases) k storing discs such as CD-ROM and CD-R are stacked. K is an apparatus for packaging with a packaging material such as a plastic film. The stacking and packaging machine 1 includes a transport unit 2 (transport path) for transporting each case k, a stacker 3 that stacks the transported cases k, for example, every 10 sheets, and feeds them as a stack unit K. Each unit K is schematically constituted by packaging means 4 (packaging machine) for packaging with a plastic film f fed out and cut from the film roll R.
[0008]
In the main part plan view of the stacking and packaging machine 1 shown in FIG. 2, the conveying means 2 includes a supply conveyor 6 and a separation conveyor 7, and a stacking device 3 is disposed at the tip of the separation conveyor 7. The supply conveyor 6 is formed by an endless belt conveyor that continuously conveys the case k, and the separation conveyor 7 is set to be conveyed at a higher speed than the supply conveyor 6 by the endless belt conveyor. Cases k that are continuously conveyed in a connected state can be separated from each other so as to have a predetermined interval.
The accumulating device 3 is accommodated in an accommodating portion 8 having, for example, a substantially rectangular parallelepiped shape formed on an extension line of the separation conveyor 7. This accommodating portion 8 has a substantially L-shaped door portion 10 in plan view that is rotatably supported by a support shaft 9 provided at a corner of the accommodating portion 8 that is substantially rectangular in a horizontal sectional view. The shaft 9 is supported by the frame 4a of the packaging means 4 via a bracket 11 having a short side that is rectangular in a horizontal sectional view. Further, the door portion 10 having an approximately L-shape is constituted by a flat substrate plate 12 positioned substantially parallel to the separating conveyor 7 and a side portion 13 orthogonal thereto, and the side portion 13 closes the door portion 10. In this state, the door 10 is positioned by being locked to the frame 4 a of the packaging means 4 by the lock lever 14.
An integrated hopper 16, a receiving elevator 17, and a drive source such as a servo motor M are attached to the substrate plate 12 of the door 10. The integrated hopper 16, the receiving elevator 17 and the drive source are integrally rotated by the opening operation of the door portion 10 and taken out of the housing portion 8, and are positioned and operated in the housing portion 8 when locked by the closing operation. It becomes possible. A grip 18 for opening and closing the door 10 is attached to the outer surface of the substrate plate 12.
[0009]
Next, the configuration of the accumulation device 3 will be described with reference to FIGS.
The integrated hopper 16 has a substantially square cylindrical shape with a bottom. Further, a fixed wall 21 that constitutes a side wall of the integrated hopper 16 and is substantially orthogonal to the terminal end of the separating conveyor 7 and a movable wall 22 that faces the fixed wall 21 are fixed to the substrate plate 12 of the door portion 10. A pair of seating plates 20a and 20b (sitting portions) constituting a seating portion of the case k are fixed to the lower inner surfaces of the fixed wall 21 and the movable wall 22. For example, three grooves or recesses (see FIG. 3) are formed in the seating plates 20a and 20b. A bottom portion between the seating plates 20a and 20b is a space S.
Further, the fixed wall 21 and the movable wall 22 are provided with a pair of side walls 19a and 19b substantially orthogonal to them. The side walls 19 a and 19 b are provided only on the upper portion of the accumulation hopper 16. The integrated hopper 16 extends in a direction substantially orthogonal to the conveying surface of the separation conveyor 7, and extends in the vertical direction substantially parallel to the standing substrate plate 12.
Then, the case k that has been transported on the separating conveyor 7 falls sequentially into the stacking hopper 16. Further, the stacking unit K of the case k stacked in the stacking hopper 16 is placed on the seating plates 20a and 20b, and a pusher 30 to be described later rises from the lower side to the upper side in the space S and moves the stacking unit K. It will be sent out into the packaging means 4 in the horizontal direction.
In FIG. 4, the fixed wall 21 extends from the seating plate 20 a to a position slightly lower than the conveyor 7, whereas the movable wall 22 extends from the seating plate 20 b to the position higher than the conveyor 7. . The distance between the movable wall 22 and the fixed wall 21 can be adjusted by shifting the movable wall 22 in the conveying direction of the separating conveyor 7.
[0010]
Next, the receiving elevator 17 (accumulation processing means) for lowering the case k in the accumulation hopper 16 will be described with reference to FIGS.
A pair of support pillars 23, 23 are fixed to the inner surface of the housing portion 8 of the substrate plate 12, and each support pillar 23 extends along the substrate plate 12 in the extending direction (vertical direction) of the integrated hopper 16. In each column 23, an elevating unit 26 having an elevating stage 24 is held so as to be movable up and down. A rodless cylinder 25 is disposed on each elevating stage 24 substantially in parallel with the substrate plate 12 and in the extending direction of the separating conveyor 7. Here, the tip of the rodless cylinder 25 on the movable wall 22 side (in the direction of the fixed wall 21) is provided with a primary comb 27-shaped primary elevator 27, and the rodless cylinder 25 on the fixed wall 21 side (in the direction of the movable wall 22). A substantially comb-shaped secondary elevator 28 is provided at the tip.
The primary and secondary elevators 27 and 28 are separated by a rodless cylinder 25 and supported so as to be able to advance and retreat in the extending direction of the conveyor 7. The primary elevator 27 extends into the integrated hopper 16 through a plurality of slit-shaped grooves provided in the movable wall 22 at the advanced position, and is located on the back side of the movable wall 22 that has retreated from the integrated hopper 16 at the retracted position. The secondary elevator 28 extends into the integrated hopper 16 through a plurality of slit-shaped grooves provided on the fixed wall 21 at the advanced position, and is positioned on the back side of the fixed wall 21 that has retreated from the integrated hopper 16 at the retracted position. In a state where both the primary and secondary elevators 27 and 28 have advanced into the accumulation hopper 16, the primary and secondary elevators 27 and 28 have alternate comb blade shapes so as to pass each other in the vertical direction. Therefore, as shown in FIG. 3, the primary elevator 27 has, for example, four comb blade shapes, and the secondary elevator 28 has, for example, three comb blade shapes.
As described above, since the seating plates 20a and 20b are formed with three grooves or recesses (see FIG. 3), the case where the secondary elevator 28 is stacked is placed on the seating plates 20a and 20b. The secondary elevator 28 can be lowered in the groove portion or the recessed portion below the upper surfaces of the seating plates 20a and 20b so that the secondary elevator 28 can be left in a state. As shown in FIG. 4, servo motors M (drive sources) for moving the elevating unit 26 for moving the primary and secondary elevators 27, 28 up and down along the column 23 are respectively the substrate plate 12 (or column 23). It is fixed to.
[0011]
The primary elevator 27 and the secondary elevator 28 are generally controlled as follows.
First, the primary elevator 27 is held at a predetermined height position (this is referred to as an initial position) slightly lower than the separation conveyor 7 in the accumulation hopper 16, and when the case k sequentially falls from the separation conveyor 7, this is received in the accumulation hopper 16. The position is lowered step by step. On the other hand, after the secondary elevator 28 has advanced to the same height as the primary elevator 27 in the integrated hopper 16, the primary elevator 27 retreats from the integrated hopper 16, so that the stacked case k is received by the secondary elevator 28. hand over.
Each time the secondary elevator 28 receives the fall of the case k, the height is lowered step by step, so that the height position for receiving the case k that is separated from the primary elevator 27 and falls from the conveyor 7 is kept constant. The primary elevator 27 that has delivered the case k moves backward from the stacking hopper 26, moves up the back side of the movable wall 22, and advances again to the initial position in the stacking hopper 16. When the number of cases k stacked by the secondary elevator 28 reaches a predetermined number, the secondary elevator 28 continuously descends and delivers the stacking unit K onto the seating plates 20a and 20b. Retreat to the back side.
The laminated unit K held in the accumulation hopper 16 is sent out to the packaging means 4 side by the pusher 30.
[0012]
Next, as shown in FIG. 3, the packaging means 4 is provided with a pair of bottom guides 32, 32 on the extension lines of the seating plates 20a, 20b of the integrated hopper 16. A path between the pair of bottom guides 32 and 32 constitutes a conveyance guide path 33 of the stacked unit K. As shown in FIG. 5, a pusher 30 is provided in the stacking hopper 16 to feed the stacking unit K along the transport guide path 33 into the packaging means 4.
The pusher 30 is formed in, for example, a U-shape when viewed from the side, and includes a distal end pusher portion 30a, a proximal end pusher portion 30b, and a connecting portion 30c that connects the pusher portions 30a and 30b. Below the pusher 30, a rodless cylinder 34 is provided as an operating means for reciprocating the pusher 30 from the integrated hopper 16 along the conveyance guide path 33 to the packaging means 4, and a holding shaft that stands up from the rodless cylinder 34. Reference numeral 35 denotes a base end pusher 30 b of the pusher 30. The pusher 30 moves up in the space S and moves in the direction of the packaging means 4, thereby allowing reciprocation along a box-shaped (rectangular) locus.
In FIG. 5, the pusher 30 is separated along the conveyance guide path 33 in a state where the accumulation unit K is sandwiched between the front end pusher part 30 a and the proximal end pusher part 30 b in the accumulation hopper 16 and substantially orthogonal to the conveyor 7. The stacking unit K between the pusher portions 30a and 30b is fed into the packaging means 4, and at the same time, the stacking unit K fed into the packaging means 4 by the previous operation is further pushed out by the tip pusher portion 30a. It is like that. Thereafter, the pusher 30 is retracted below the stacking unit K by the holding shaft 35 and moves to the lower part of the space S in the stacking hopper 16.
In the present embodiment, the pusher 30 is not supported by the substrate plate 12 and is configured as a part of the packaging means 4.
[0013]
The stacking and packaging machine 1 according to the present embodiment has the configuration of the stacking device 3 as described above, and the operation thereof will be described next.
First, the conveyance and accumulation processing of the case k by the accumulation packaging machine 1 will be described with reference to FIGS.
In FIG. 6, the secondary elevator 28 leaves the integrated unit K stacked in a predetermined total number of stages (10 in the figure) on the seating plates 20 a and 20 b and is being pulled out from the integrated hopper 16 to the back side of the fixed wall 21. is there. Further, the stacking unit K is held by the pusher 30 and starts to be conveyed. On the other hand, the primary elevator 27 is located on the upper back surface of the movable wall 22.
Then, as shown in FIG. 7, the primary elevator 27 enters the stacking hopper 16 at an initial position height slightly lower than the separation conveyor 7, and the secondary elevator 28 is pulled out from the stacking hopper 16 to the back surface of the fixed wall 21. Is in a state. The pusher in the accumulation hopper 16 sends out the accumulation unit K toward the packaging means 4. Next, the primary elevator 27 receives the case k, which is separated from the conveyor 7 by being separated in the accumulation hopper 16, and the pusher 30 descends from the conveyance guide path 33 after transferring the accumulation unit K into the packaging means 4. (See FIG. 8).
The primary elevator 27 descends one step in the stacking hopper 16 and then descends step by step each time the case k is received so as to receive the case k sequentially sent from the separating conveyor 7 at a predetermined height. On the other hand, the secondary elevator 28 stops at a predetermined height position on the back surface of the fixed wall 21 (see FIG. 9).
[0014]
Next, when the primary elevator 27 descends in the accumulation hopper 16 and reaches the same height position as the secondary elevator 28, the secondary elevator 28 enters the accumulation hopper 16 through the slit-like groove portion of the fixed wall 21. . In this state, the elevators 27 and 28 are in a state in which the mutual comb blades are fitted in the gaps between the mutual comb blades as shown in FIG. 3 (see FIG. 10). On the other hand, the pusher 30 is returned to the lower part of the accumulation hopper 16 and ascends in the gap S between the seating plates 20a and 20b.
In this state, the primary elevator 27 delivers a plurality of cases k stacked on the secondary elevator 28 and retreats from the integrated hopper 16 through the groove portion of the movable wall 22. The pusher 30 reaches the receiving height of the stacking unit K in the stacking hopper 16 and stops (see FIG. 11). Next, the secondary elevator 28 is lowered step by step every time the case k is received so as to receive the case k that sequentially falls from the separation conveyor 7 at a predetermined height.
Then, for example, at the stage where 10 sheets are stacked to form the stacked unit K, the secondary elevator 28 is continuously lowered, and the stacked unit K is seated on the seating plates 20a and 20b, and the distal end pusher portion 30a and the proximal end of the pusher 30 are placed. It is also placed on the connecting portion 30c between the pusher portion 30b. Thereafter, the secondary elevator 28 sinks into the groove portions of the seating plates 20 a and 20 b, so that the integrated unit K is transferred onto the seating plates 20 a and 20 b and the connecting portion 30 c of the pusher 30, and retracts to the back surface of the fixed wall 21. Further, the primary elevator 27 ascends the back surface of the movable wall 22 and reaches the initial position height in the vicinity of the separation conveyor 7 (see FIG. 12).
By repeating such an operation, the integrated unit K in which a predetermined number of cases k are stacked is sequentially fed into the packaging means 4 by the pusher 30 and then packaged by the film f. Moreover, the case k can be accumulated and discharged as the accumulation unit K by the receiving elevator 17 while being continuously conveyed at a predetermined interval without temporarily stopping the case k by the conveyance means 2.
[0015]
Further, when repairing, maintaining or inspecting the stacking apparatus 3, the door 10 is opened by holding the grip 18 and opening the door 10 from the accommodating portion 8 around the support shaft 9 as shown in FIG. (Non-operational position) The integrated hopper 16 attached to the inner surface of the substrate plate 12, the receiving elevator 17, the servo motor M and the like are off the line and exposed outside the housing portion 8. Therefore, repair, maintenance, inspection, etc. of the accumulation hopper 16, the receiving elevator 17, the servo motor M, etc. can be performed without separating and disassembling the accumulation apparatus 3 from the conveying means 2 or the packaging means 4 to which the accumulation apparatus 3 is connected.
Even when the door portion 10 is closed, the side portion 13 is locked to the frame 4a of the packaging means 4 by the lock lever 14 by holding the grip 18 and closing it around the support shaft 9 (operation position). . In this state, the stacking device 3 is accurately positioned with respect to the front and rear transport means 2 and the packaging means 4, so that the case k transported from the separating conveyor 7 can be reliably dropped into the stack hopper 16 and the seating plate 20a. , 20b can be transported in the transport guide path 33 by the pusher 30 toward the packaging means 4 reliably.
[0016]
As described above, according to the present embodiment, the stacking hopper 16, the receiving elevator 17, the servo motor M, etc. of the stacking device 3 are attached to the substrate plate 12 of the door portion 10 on one side, which is compact and occupies a small space. That's it. Moreover, it is very easy to take out the case k located in the stacking device 3 in the non-actuated position where the door 10 is opened, clean the interior of the stacking device 3, check it, perform maintenance work, and close the door 10. The integrated hopper 16, the receiving elevator 17, the servo motor M, and the like, which are each component of the stacking device 3, can be positioned at the operated position.
[0017]
In the above-described embodiment, the pusher 30 for sending out the stacking unit K of the case k is provided in the packaging means 4. However, the pusher 30 may be included in the stacking device 3 and attached to the door 10. . Next, a modified example of the integrated packaging machine 1 according to the above-described embodiment will be described with reference to FIGS. 13 and 14. The same reference numerals are used for the same or similar members and parts as those of the above-described embodiment. I will explain.
13 and 14, the substrate plate 12 of the door portion 10 is provided with a case auxiliary portion 40 that protrudes in a substantially cylindrical shape that protrudes in a direction orthogonal to the substrate plate 12, for example, a rectangular tube shape. A rodless cylinder 41 (actuating member) is disposed below the seating plates 20 a and 20 b of the integrated hopper 16 so as to be able to advance and retract in a direction substantially orthogonal to the substrate plate 12. The rodless cylinder 41 is slidably held on the substrate plate 12.
A horizontal transfer pusher 42 is attached to the upper portion of the rodless cylinder 41, and the pusher 42 sends out the stacking unit K placed on the seating plates 20 a and 20 b in the stacking hopper 16 and wraps it through the transfer guide path 33. 4 is transferred to the inside. The rodless cylinder 41 and the pusher 42 reciprocate linearly, and are accommodated in the case auxiliary portion 40 so as to advance and retreat. The space S between the seating plates 20a and 20b has a width that allows the horizontal transfer pusher 42 to reciprocate.
The rodless cylinder 41 and the horizontal transfer pusher 42 are included in the stacking device 3. In addition to the stacking hopper 16, the receiving elevator 17 and the servo motor M, the rodless cylinder 41 and the horizontal transfer pusher 42 also slide on the substrate plate 12. It is attached on one side as possible. Therefore, when the door portion 10 is opened around the support shaft 9, the rodless cylinder 41 and the horizontal transfer pusher 42 rotate together with the integrated hopper 16, the receiving elevator 17, the servo motor M and the like for repair, maintenance and inspection. It will be easy to do.
[0018]
In the above-described embodiment, the door portion 10 is formed in a substantially L-shape including the substrate plate 12 and the side portion 13, but the door may be formed only by the substrate plate 12.
In the above-described embodiment and the like, each part of the stacking device 3 is mounted on one side of the openable / closable door 10 centered on the support shaft 9, but the present invention is not limited to such a configuration. Absent. For example, the stacking hopper 16, the receiving elevator 17, the servo motor M, etc. of the stacking apparatus 3 are attached on one side to a plate-like substrate plate including a rodless cylinder 41 and a horizontal transfer pusher 42 in addition to these components. A state in which the substrate plate is slid on the rail along its longitudinal direction so that it is mounted in the accommodating portion 8 and held in the operating position, or taken out from the accommodating portion 8 and held in the non-operating position and removed from the line. It may be possible to perform maintenance such as repair, maintenance and inspection.
In addition, the work to be accumulated in the present invention is not limited to the case k such as a disk, and can be applied to various products.
[0019]
【The invention's effect】
As described above, in the stacking apparatus according to the present invention, the stacking hopper that holds the workpieces supplied from the conveyance path in a stacking state and the stacking processing means for sequentially stacking the workpieces supplied in the stacking hopper are attached to the substrate. Since the substrate can selectively take an operation position for accumulating the workpieces supplied from the conveyance path and a non-operation position where the accumulation hopper and the accumulation processing means are removed from the operation position, the substrate is held in the operation position. The workpieces transported in (1) can be smoothly fed into the stacking hopper and sequentially stacked by the stacking processing means, and when the substrate is moved to the non-operating position, it is detached from the line and repair, maintenance and inspection of the stacking hopper and the stacking processing means are performed. Maintenance work such as this can be facilitated. Moreover, since the integration device is configured to be mounted on one side of the substrate, the assembly work of each component such as the integration hopper and the integration processing means is simple and easy.
[0020]
Further, since the pusher for discharging the work accumulated in the accumulation hopper is further attached to the substrate, the parts can be further assembled and mounted, and repair, maintenance, inspection and the like can be performed more easily.
In addition, since the substrate is a door provided between the conveyance path and the packaging means, it is possible to hold each component such as the integrated hopper and the integrated processing means in the operating position by closing the door, and by opening the door. The parts such as the integrated hopper and the integrated processing means can be moved to a non-operating position where the work can be easily performed, and repair, maintenance, and inspection can be easily performed.
