Description

  The present invention relates to a workpiece continuous supply device that continuously supplies workpieces to a filling device and a workpiece filling device that fills a container with the supplied workpieces.

  Conventionally, bottle-type gums in which a wide-mouthed container made of resin or the like is filled with a tablet-like gum have been manufactured and sold. Since the gum filled in the container is not wrapped in wrapping paper, in order to wrap and discard the chewing gum, a bundle of discarded paper is usually put in one bundle for each bottle (for example, patent document) 1).

Moreover, when filling a container such as the above with gum or the like, various workpiece filling devices are used. For example, Patent Document 2 discloses a workpiece filling and packaging apparatus including a plurality of filling mechanisms for weighing a workpiece such as a bag and filling a bag-like container.

  By the way, since the above-mentioned discarded paper bundle is different in shape and size from the gum to be filled, it is difficult to fill it with the same work filling apparatus as the gum. Further, since the discarded paper bundle itself is not food, it is not preferable from the viewpoint of hygiene to fill it with the same work filling device as the gum. In addition, since the number of fillings is as small as one bundle (that is, one piece) for one container, the present situation is that filling of the discarded paper bundle is performed manually.

  However, since the above manual work is performed by humans, there is an upper limit in speed. Therefore, even if it is attempted to increase the manufacturing efficiency by increasing the speed of other processes, there is a problem that the manual operation becomes a bottleneck and the total efficiency of the manufacturing process is not easy.

  This invention is made | formed in view of the said situation, and it aims at providing the workpiece | work continuous supply apparatus and workpiece | work filling apparatus which can supply a workpiece | work to a filling mechanism automatically continuously.

  FIG. 5 is a view of the replenishment work installation unit 7 and the first conveyor 6 as viewed from the second conveyor 10 side. Each slot rail 12 has a longitudinal end portion connected by a chain 16. The chain 16 is wound around sprockets 14 provided at both ends in the traveling direction. A driving mechanism (not shown) such as a motor is attached to the sprocket 14.

  That is, the slot rails 12 and the work slots 15 are configured to move around the first conveyor 6 sequentially by the chain 16 and the sprocket 14 and then circulate through the lower part of the first conveyor 6. The sprocket 14 is adjusted so as to rotate by a predetermined pitch so that the moved work slot 15 is always located directly above the first conveyor 6. The bottom plate 13 is disposed below the upper slot rail 12 and at a position higher than the chain 16 and the first conveyor 6.

  6 is a cross-sectional view taken along line XX in FIG. As shown in FIG. 6, each slot rail 12 has an inverted U-shaped cross section, and an end 12 </ b> A in the longitudinal direction is fixed to the chain 16. The bottom plate 13 is disposed in a space between the end portions 12A.

FIG. 7 is an enlarged plan view near the boundary between the first conveyor 6 and the second conveyor 10. Guides 17 for guiding the work from the first conveyor 6 to the second conveyor 10 are provided on the left and right sides of the portion where the first conveyor 6 and the second conveyor 10 face each other. Each guide 17 is configured such that its tip can protrude and retract toward the first conveyor 6 by a moving mechanism (not shown). Each guide 17 is integrally formed with a side surface portion 18 that restricts movement of the workpiece in the width direction and a bottom surface portion 19 that restricts movement of the workpiece in the height direction. An end portion of the side surface portion 18 on the first conveyor 6 side slightly extends in the outer direction of the first conveyor 6.
A plate-like shutter 20 is provided on the left side of the end of the first conveyor 6 on the supply passage 5 side with respect to the moving direction of the first conveyor 6. The shutter 20 is disposed so as to be able to shield between the first conveyor 6 and the second conveyor 10 by a moving mechanism (not shown).

  A first sensor 21 for monitoring the workpiece supply state is provided on the right side of the moving direction of the first conveyor 6 and in the vicinity of the end on the second conveyor 10 side. A second sensor 22 that takes the operation timing of the shutter 20 is provided on the right side with respect to the moving direction of the second conveyor 10 and in the vicinity of the boundary with the first conveyor 6 side. A third sensor 23 that detects a workpiece supply abnormality is provided at a position on the vertical portion 8 side by a predetermined distance from the second sensor 22. The first sensor 21, the second sensor 22, and the third sensor 23 are all configured by known sensors such as a reflection type and a transmission type.

The filling unit 3 includes a star wheel 24 that takes in containers from the main conveyor 1, a partition plate 25 provided on the top of the star wheel 24, and a work conveyance unit 26 provided on the top of the partition plate 25.
As shown in FIG. 1, the star wheel 24 is provided with a plurality of cutouts 27 that are substantially semicircular in plan view along a periphery of a member made of a cylindrical resin or the like. A rotation member serving as a rotation axis is fixed to the central axis of the star wheel 24. The rotating member is connected to a driving mechanism such as a motor (not shown), and the star wheel 24 is configured to be rotatable about the rotating member 28 as a rotating shaft. In FIG. 1, in order to make the shape of the star wheel 24 easier to see, the partition plate 25 and the work transporting portion 26 are omitted.

  The partition plate 25 is, for example, a semicircular member obtained by cutting a part of the disk, and is fixed to the upper portion of the star wheel 24 as shown in FIG. Since the partition plate 25 is not fixed to any of the star wheel 24 and the rotating member 28, the partition plate 25 is not rotated even when the star wheel 24 rotates, and is fixed to the position shown in FIG.

The work conveyance unit 26 is a plate-like member having substantially the same thickness as the work W, and the same number of through holes 29 as the cutouts 27 of the star wheel 24 are provided. . Each through hole 29 is arranged in a positional relationship such that one through hole 29 exists above each notch 27, and is fixed to the rotating member 28. That is, when the star wheel 24 is rotated, the work transporting portion 26 is also rotated.
Further, the respective through holes 29 are arranged on the same circumference with the rotary member 28 as the center, and the vertical portion 8 is disposed at an upper portion of one point on the circumference. At the position where the vertical portion 8 is disposed, the partition plate 25 blocks the through hole 29 and the notch 27.

Operations of the filling device 1 and the supply device 5 configured as described above will be described with reference to FIGS.
First, an operator installs a row of replenishment works in each work slot 15 located on the bottom plate 13. At the same time, workpieces are also installed on the first conveyor 6 and the supply passage 5.

  When the filling device 1 is activated, the first conveyor 6 is started and the work is sent to the supply passage 5. At this time, as shown in FIGS. 8A and 8B, each guide 17 protrudes toward the first conveyor 6, and the work smoothly enters the supply passage 5 by the side surface portion 18 and the bottom surface portion 19. Sent. Thereafter, as shown in FIG. 4, the workpiece W is sent from the inclined portion 9 to the vertical portion 8 by the second conveyor 10. The lowermost work W1 of the vertical portion 8 enters the through hole 29 when the through hole 29 provided in the work transporting portion 26 that rotates about the rotating member 28 passes under the vertical portion 8. .

  The workpiece W <b> 1 inside the through-hole 29 is detached from the workpiece row accommodated in the vertical portion 8 by the rotation of the workpiece conveyance unit 26. As described above, since the space between the through hole 29 and the notch 27 of the star wheel 24 is blocked by the partition plate 25, the work inside the through hole 29 is the work transporting portion 26, the star wheel 24, and the main conveyor. 2 rotates together with a container C filled with gum (not shown) taken into the notch 27.

  When the star wheel 24 and the work transporting portion 26 are rotated to a portion where the partition plate 25 is not provided, the through hole 29 and the notch 27 communicate with each other, so that the work W is filled and charged into the container C. The container C loaded with the workpiece W returns to the main conveyor 2 again and is sent to the next process (not shown).

Next, operation | movement of the supply apparatus 4 when the workpiece | work W is replenished to the 1st conveyor 6 is demonstrated with reference to FIGS.
When the work on the first conveyor 6 is sent to the supply passage and decreases, the work is not detected by the first sensor 21 shown in FIG. When the first sensor detects this state, a signal is transmitted to a control unit (not shown).

  The control unit that has received the signal moves the pressure 11 through a moving mechanism (not shown) so that the workpiece W of the inclined unit 9 does not fall down later, as shown in FIGS. 8 (a) and 8 (b). Press the rear side of the workpiece W. When the pressure 11 moves a predetermined distance and passes in front of the second sensor 22, the control unit moves the guide 17 toward the supply passage 5 as shown in FIGS. 9 (a) and 9 (b). Subsequently, the shutter 20 is moved between the first conveyor 6 and the supply passage 5 to be shielded.

  The control unit rotates the sprocket 14 by a predetermined pitch amount to move the replenishment work W2 in the slot rail 12 and the work slot 15 to the first conveyor 6 side as shown in FIG. The replenishment work W2 in the work slot 15A adjacent to the first conveyor 6 moves to just above the first conveyor 6 and stops.

  At this time, since the bottom plate 13 does not exist under the work slot 15A, the replenishment work W2 moves downward. Thus, as shown in FIGS. 10A and 10B, the replenishment work W <b> 2 is replenished onto the first conveyor 6.

  The work W supplemented to the first conveyor 6 is pressed toward the shutter 20 by the first conveyor 6. Then, the workpiece W is detected by the first sensor 21 and transmitted to the control unit.

As shown in FIG. 11A, the control unit returns the shutter 20 to the original position to open the space between the first conveyor 6 and the second conveyor 10, and simultaneously moves the guide 17 to the original position. Projecting to the first conveyor 6 side.
Thereafter, the workpiece W is sent to the second conveyor 10 while being aligned by the guide 17. At the same time, the pressure 11 retreats above the supply passage 5 and returns to a predetermined position as shown in FIG. In this way, the replenishment of the workpiece W is completed.

  Since the series of operations described above is completed with the work W remaining in the supply passage 5, the supply device 4 does not stop during the work replenishment. Accordingly, the filling device 1 continuously performs the work filling operation until all the replenishment work W2 installed in the replenishment work installation unit 7 is eliminated.

  In addition, in the unlikely event that some abnormality occurs in the workpiece supply device 4 and the workpiece W is not supplied to the second conveyor 10, it is detected by the third sensor 23 that the workpiece W has been lost, and the supply to the control unit is abnormal. Is transmitted. The control part which received the said signal stops the filling apparatus 1 whole. This prevents the unfilled container from being sent to the next process.

  According to the supply device 4 of the present invention, the replenishment work installed in the replenishment work installation unit 7 is automatically replenished to the first conveyor 6 and continuously supplied to the supply passage 5. Therefore, the workpiece can be continuously supplied to the filling apparatus 1 at a high speed for a long time. Further, according to the filling device 1 of the present invention, since the workpiece is continuously supplied from the supply device 4 for a long time, a filling device that can be operated unattended for a long time can be configured.

  When the work W on the first conveyor 6 decreases, the first sensor 21 automatically detects and the rear part of the work W decreased by the pressure 11 is pressed. Accordingly, it is possible to prevent the supply device 4 from being stopped due to the workpiece W falling on the first conveyor 6 or the second conveyor 10.

  Further, when the work W is replenished from the replenishing work installation unit 7 to the first conveyor 6, the shutter 20 supports the front of the replenished work and prevents the work W from falling down. Accordingly, it is possible to make the supply device 4 more difficult to stop, and to prevent foreign matters and the like from entering the supply passage 5.

  Further, since the guide 17 is provided so as to bridge between the first conveyor 6 and the second conveyor 10, even if the row is slightly disturbed when the work W is replenished to the supply passage 5, The side surface 18 can smoothly guide the workpiece W to the supply passage 5.

  Furthermore, since the guide 17 is provided with the bottom surface portion 19, it is possible to prevent the workpiece W from falling into the gap between the first conveyor 6 and the second conveyor 10. Therefore, it is possible to configure a supply device that is less likely to cause clogging of workpieces.

Furthermore, since the operation timings of the pressure 11, the shutter 20, and the guide 17 are optimally adjusted by the first sensor 21 and the second sensor 22, the replenishment of the workpiece can be completed smoothly.
In addition, even when some abnormality occurs in the supply device 4 and the supply of the work to the supply passage 5 is interrupted, the abnormal state is detected by the third sensor 23 and the entire filling device 1 is stopped. It is possible to prevent inconveniences caused by sending uncontained containers to the next process.

Although the embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. .
For example, in the above-described embodiment, an example of an apparatus that supplies and fills a discarded paper bundle of gums has been described.
