Embodiment 1 Workpiece Cutting Device 10
First, based on FIG. 1, the structure of the workpiece cutting device 10 which concerns on Embodiment 1 of this invention is demonstrated. (A) of FIG. 1 is a side view showing the structure of the workpiece cutting device 10 when viewed from the conveyance direction by a single-line conveyance conveyor 6 described later. Moreover, (b) of FIG. 1 is a top view which shows a structure when the workpiece cutting device 10 is seen from the upper side. The workpiece cutting device 10 is a device that cuts out a predetermined number of bottle containers from a multi-row bottle container (work) conveyed by the multi-row conveyor 1, and conveys the cut-out predetermined number of rows of workpieces downstream. is there. In the following, for simplicity, the workpiece cutting apparatus 10 will be described with respect to a mode in which single row bottle containers are cut out from multi-row bottle containers and the single row bottle containers are transported downstream. However, the number of rows of bottle containers cut out from the multi-row bottle containers is not limited to one row and may be two or more rows.

  As shown to (a) of FIG. 1, the workpiece cutting device 10 is the multi-row conveyance conveyor 1, the upstream opposing guide 2, the bottle receiving stand (holding member) 3, the bottle raising / lowering stand (elevating member) 4, and the extrusion guide 5. , A single row conveyor (conveyor) 6, and a downstream facing guide 7.

(Multi-line conveyor 1)
The multi-row transport conveyor 1 is a device that transports a multi-row bottle container toward a terminal portion of the multi-row transport conveyor 1 by rotating (driving) a belt. Hereinafter, the side on which the multi-row bottle containers are transported is referred to as the upstream side of the workpiece cutting device 10 as viewed from the side on which the cut single-row bottle containers are transported. In addition, when viewed from the side where the multi-row bottle containers are conveyed, the side where the cut single-line bottle containers are conveyed is referred to as a downstream side of the workpiece cutting apparatus 10.

(Upstream facing guide 2, bottle cradle 3)
The bottle cradle 3 can store a single row of bottle containers on the cradle. At the first height, the bottle cradle 3 receives a single row of bottle containers from the multi-row transport conveyor 1, and at the first height, It is a member that temporarily holds a single row of bottle containers before being lowered by a pedestal of the bottle lifting platform 4 to be described later. Here, the “first height” is the height of the bottle container when being transported by the multi-row transport conveyor 1. The “second height” is the height of the bottle container when the cut single-line bottle container is transported by the single-line transport conveyor 6. The height reference may be the center of gravity of the bottle container or the center of the bottle container. Further, the height of the head of the bottle container may be used as a reference for the height, and the height of the bottom of the bottle container may be used as a reference for the height.

  The bottle cradle 3 is configured such that the cradle slides in the shutter-type lateral direction (the transport direction of the multi-row transport conveyor 1) at the first height and approaches the terminal portion of the multi-row transport conveyor 1 And the operation of pulling away from the end portion are alternately repeated.

  When the cradle of the bottle cradle 3 is completely extended to the end portion side of the multi-row transport conveyor 1, a single-row bottle container, which is a bottle container for one row at the end of the multi-row bottle container, is transported in multiple rows. It is fed onto the cradle of the bottle cradle 3 by the rotation of the belt of the conveyor 1. In addition, one end of the single row bottle container that is fed onto the cradle of the bottle cradle 3 by the rotation of the belt of the multi-row transport conveyor 1 comes into contact with (arrives) the upstream facing guide 2. Thereby, the progress of the single row bottle container sent onto the cradle of the bottle cradle 3 is prevented. The upstream facing guide 2 can be adjusted in the vertical direction according to the bottle size.

  By the operation in which the cradle of the bottle cradle 3 is pulled away from the terminal end of the multi-row transport conveyor 1, the single row bottle containers that are prevented from advancing due to contact with the upstream facing guide 2 are detached from the cradle, A slight drop is dropped on the pedestal of the bottle lifting platform 4 that exists directly under the cradle. As a result, the single row bottle containers are transferred from the cradle of the bottle cradle 3 to the base of the bottle lifting platform 4 at the first height. In addition, the bottle cradle 3 temporarily holds the subsequent single row bottle containers on the cradle of the bottle cradle 3 at least during a period when the pedestal of the bottle lifting / lowering base 4 rises from the second height to the first height. . Therefore, by appropriately adjusting the holding timing of the single row bottle container by the cradle of the bottle cradle 3, the separation process of the multi-row bottle container and the bottle container supply process to the downstream side are simultaneously operated. It is possible to improve the driving performance by shortening the one-cycle operation time.

(Bottle lift 4)
The bottle lifting platform 4 is a member that lowers the single row bottle containers transferred from the bottle receiving platform 3 at the first height as described above from the first height to the second height.

  The bottle lifting / lowering table 4 includes a pedestal, and an operation in which the pedestal moves upward in the vertical direction and an operation in which the pedestal descends in the vertical direction are alternately repeated. That is, the bottle lifting platform 4 is moved up and down between the first height and the second height. By the pulling operation of the cradle of the bottle cradle 3, the single row bottle containers are removed from the cradle and drop a little drop, and are transferred onto the base of the bottle lifting / lowering base 4. The pedestal of the bottle lifting platform 4 is lowered from the first height to the second height in a state where the transferred single row bottle containers are placed, and conveys the single row bottle containers downstream. Thereby, the single row bottle container separated from the multi-row bottle container can be conveyed downstream.

(Extrusion guide 5, single row conveyor 6, downstream side opposing guide 7)
The extrusion guide 5 is configured to push the single row bottle container on the base of the bottle lifting / lowering table 4 that has been completely lowered to reach the second height onto the belt of the single row conveyer 6, and the single row conveyance after the extrusion. The operation of pulling away from the vicinity of the belt of the conveyor 6 is alternately repeated.

  The single row bottle containers on the pedestal of the bottle lifting / lowering table 4 that has been completely lowered and reached the second height are fed onto the belt of the single row conveyor 6 by the push-out operation of the push-out guide 5. At this time, the belt of the single-line transport conveyor 6 stops rotating (running) and prevents the container bottle being transferred from falling. In addition, one end of the single row bottle container fed onto the belt of the single row conveyor 6 by the extrusion guide 5 abuts (arrives) against the downstream facing guide 7. Thereby, the progress of the single row bottle containers sent onto the belt of the single row conveyor 6 is prevented. Each of the extrusion guide 5 and the downstream facing guide 7 described above can be adjusted in the vertical direction according to the bottle size.

  The single row conveyor 6 conveys the single row bottle containers fed onto the belt by the extrusion guide 5 in a direction substantially perpendicular to the conveyance direction of the multi-row conveyor 1 by rotating (running) the belt. It is supposed to be.

(About the operation | movement flow of the workpiece cutting device 10)
Next, based on FIGS. 2-6, the flow of operation | movement of the workpiece | work cutting-out apparatus 10 mentioned above is demonstrated. First, as shown in FIG. 2 and FIG. 3, a bottle cradle that protrudes in the vicinity of the end portion of the multi-row transport conveyor 1 as the belt of the multi-row transport conveyor 1 on which the multi-row bottle containers are mounted rotates (runs). 3, the single row bottle container comes into contact with the upstream opposite guide 2 at the first height by the force of the subsequent bottle container pushing the preceding bottle container, and is used for arrival confirmation described later. It is sent until it is detected by the sensor. Thereby, the bottle receiving stand 3 receives a single row bottle container from the multi-row transport conveyor 1 at the first height.

  Next, as shown in FIG. 4 and FIG. 5, after the base of the bottle lifting / lowering table 4 arrives just below (first height) the receiving platform of the bottle receiving platform 3, the receiving platform of the bottle receiving platform 3 performs a pulling operation. In general, at a first height, a single row of bottle containers that fall with a slight drop on the pedestal of the bottle lifting platform 4 is passed. Accordingly, the bottle container is transferred from the cradle of the bottle cradle 3 to the pedestal of the bottle lifting platform 4 at a first height.

  Next, as shown in FIGS. 5, 6, and 2, the single-row transport conveyor 6 that is a belt conveyor that transports the single-row bottle containers from directly below the first base of the bottle tray 3 (first height). The base of the bottle lifting platform 4 is lowered to the level of the belt (second height). After descending, the cradle of the bottle cradle 3 performs an overhanging operation and repeats the bottle feeding operation shown in FIGS.

  Next, as shown in FIGS. 6 and 2, the bottle container placed on the pedestal of the bottle lifting / lowering table 4 at the second height is moved on the belt of the single-line transport conveyor 6 by the operation of extending the extrusion guide 5. Transfer to At this time, the belt of the single-line transport conveyor 6 stops rotating (running) and prevents the container bottle being transferred from falling.

  Next, as shown in FIGS. 2 to 4, the push-out guide 5 moves back after the bottle container is transferred onto the belt of the single-line transport conveyor 6, and then the pedestal of the bottle lifting platform 4 receives the bottle holder. It is raised to just below the pedestal of the base 3 (first height).

  As shown in FIG. 3 and FIG. 4, the bottle cradle 3 temporarily holds subsequent single row bottle containers to be cut out during a period when the bottle lifting platform 4 rises at least from the second height to the first height. . As described above, by appropriately adjusting the holding timing of the single row bottle containers to be cut out by the bottle cradle 3, the step of separating the multi row bottle containers and the step of supplying the bottle containers to the downstream side can be performed simultaneously. It is possible to operate, and the one-cycle operation time can be shortened to improve the driving ability.

  Next, the belt of the single row conveyor 6 rotates (runs) after confirming the transfer of the bottle containers, and conveys the bottle containers to the downstream side. For the pedestal of the bottle lifting platform 4, the operation shown in FIGS. 4 and 5 is repeated after ascending.

(Effect of the workpiece cutting device 10)
As described above, according to the workpiece cutting device 10 of the present embodiment, the bottle lifting platform 4 (its pedestal) is lowered from the first height to the second height with the single row bottle containers placed thereon. It is like that. For this reason, the deterioration of the quality of the bottle container to convey can be suppressed compared with the structure which drops the bottle container disclosed by the said patent document 2 or 3 via a comparatively long drop chute or a downward passage.

  Moreover, according to the workpiece cutting device 10, the bottle cradle 3 (its cradle) temporarily holds the single row of bottle containers before being lifted and lowered by the bottle cradle 4 (its pedestal). Yes. Specifically, the bottle cradle 3 temporarily holds the subsequent single row bottle containers at least during the period when the bottle lifting platform 4 rises from the second height to the first height. For this reason, by appropriately adjusting the holding timing of the single row bottle containers by the cradle of the bottle cradle 3, the separation process of the multi-row bottle containers and the supply process of the bottle containers to the downstream side can be performed simultaneously. It is possible to operate, and the one-cycle operation time can be shortened to improve the driving ability. Moreover, since the workpiece cutting device 10 has a simple configuration, the cost can be reduced as compared with the technique disclosed in Patent Document 1.

  As described above, according to the workpiece cutting device 10, it is possible to suppress the deterioration of the quality of the bottle container to be conveyed, reduce the cost, shorten the one-cycle operation time, and improve the driving ability.

  Next, the conventional general-purpose one-row cutting apparatus performs a series of operations from the step of separating the multi-row bottle containers one by one to the step of supplying the bottle containers to the downstream side. It has a structure that cannot be operated with a certain capacity or more from time.

  The workpiece cutting apparatus 10 according to the present embodiment divides (joint operation) the step of separating the multi-row bottle containers one by one and the step of supplying the single-row bottle containers to the downstream side. By integrating with the bottle lifting platform 4 and the extrusion guide 5, the operation cycle time of the workpiece cutting device 10 can be shortened.

  In addition, since the workpiece cutting device 10 according to the present embodiment can realize single-row from multi-row, there is no need for a commonly used single-row device (single liner, etc.), and a reduction in installation space (no device required). It is possible to make proposals that lower the cost of equipment installation.

  Conventionally, when the long-angle bottle and the round bottle are combined, the configuration of the single row apparatus is different, and apparatuses for each are required. For this reason, the complexity of the configuration and the installation location differed greatly. With the workpiece cutting device 10 of this embodiment, both bottles can be used together, and the entire device can be compactly accommodated. Furthermore, according to the workpiece cutting device 10, it is possible to supply a bottle to a downstream machine without making a supply shortage even if a high-capacity line is made into a single row.

[Embodiment 2: Work cutting device 20]
Next, the configuration of the workpiece cutting device 20 according to the second embodiment of the present invention will be described based on FIGS. 7 and 8B to 8I. FIGS. 7A to 7C are side views showing structures when the workpiece cutting device 20 is viewed from the transport direction of the single-row transport conveyor 6a.

  The workpiece cutting device 20 of the present embodiment is such that the vertical relationship between the multi-row conveyor 1a and the single-row conveyor 6a is opposite to the vertical relationship between the multi-row conveyor 1 and the single-row conveyor 6 described above. This is different from the workpiece cutting device 10 of the first embodiment.

  Moreover, the workpiece cutting device 20 of this embodiment is replaced with the bottle receiving base 3 and the bottle raising / lowering base 4 with which the workpiece cutting device 10 of Embodiment 1 is equipped, the bottle holding member (holding member) 3a and the lifting device (lifting member). It differs in that it has 4a.

  Furthermore, the workpiece cutting device 20 of the present embodiment is different from the workpiece cutting device 10 of the first embodiment in that the workpiece cutting device 20 includes a guide member (guide member) 8b, and the push-out guide 7a includes a suction portion 7b.

(Upstream facing guide 2a, bottle holding member 3a)
The bottle holding member 3a can store a single row of bottle containers on the cradle. At the first height, the bottle holding member 3a receives the single row of bottle containers from the multi-row transport conveyor 1a, and at the first height, This is a member that temporarily holds a single row of bottle containers before being lifted by a lifting device 4a described later. Here, the “first height” is the height of the bottle container when being transported by the multi-row transport conveyor 1a. The “second height” is the height of the bottle container when the cut-out single row bottle container is conveyed by the single row conveyance conveyor 6a. The height reference may be the center of gravity of the bottle container or the center of the bottle container. Further, the height of the head of the bottle container may be used as a reference for the height, and the height of the bottom of the bottle container may be used as a reference for the height.

  The cradle of the bottle holding member 3a is designed to hold the cut single row of bottle containers, and to prevent the falling of the single row of bottle containers as shown in FIG. The operation of rising as shown in FIG. 7B is repeated alternately. Here, the operation for preventing the progress of the bottle container may be a rotary type or a lift type. For example, as shown in (h) and (i) of FIG. 8, instead of the rotary bottle holding member 3 a, the bottle container is prevented from progressing by using a liftable bottle holding member (holding member) 3 b. Also good.

  When the cradle of the bottle holding member 3a is overturned as shown in FIG. 7C, a single row bottle container which is a bottle container for one row at the end of the multi row bottle container is conveyed in multiple rows. It is fed onto the cradle of the bottle holding member 3a by the rotation of the belt of the conveyor 1a. In addition, one end of the single row bottle container sent onto the cradle of the bottle holding member 3a by the rotation of the belt of the multi-row transport conveyor 1a comes into contact (arrives) with the upstream facing guide 2a. Thereby, the progress of the single row bottle containers sent onto the cradle of the bottle holding member 3a is prevented. The upstream facing guide 2a can be adjusted in the vertical direction according to the bottle size.

  Further, as shown in FIG. 7C and FIG. 7A, the bottle holding member 3a has a work gripping arm of a lifting device 4a, which will be described later, descends from the second height to the first height. The subsequent single row bottle containers are temporarily held until the head of the single row bottle containers is gripped by the work gripping arm. For this reason, by appropriately adjusting the holding timing of the single row bottle containers by the cradle of the bottle holding member 3a, the separation process of the multi-row bottle containers and the bottle container supply process to the downstream side can be performed simultaneously. It is possible to operate, and the one-cycle operation time can be shortened to improve the driving ability.

(Lifting device 4a)
As shown in FIGS. 7 (a) and 7 (b), the lifting device 4a receives and receives the single row of bottle containers on the cradle of the bottle holding member 3a by the work gripping arm. It is a member that conveys (lifts) a single row of bottle containers from the bottom to the top. The method of gripping the bottle container may be a chuck type, a vacuum type, a picker type, or the like. For example, as shown in FIGS. 8B and 8C, a vacuum lifting device 4b may be used instead of the chuck lifting device 4a. Further, as shown in FIG. 8D, a picker (inner surface) type lifting device (lifting member) 4c that inflates a balloon and holds the bottle may be used. Further, a picker (outer surface) type lifting device (elevating member) 4d as shown in FIG. 8 (e) may be used.

  At the first height, the lifting device 4a lifts the single row of bottle containers from the bottom to the top (from the first height to the second height) by grasping the heads of the single row bottle containers with the workpiece gripping arm. After being raised, the bottle container is held by the guide member 8b as shown in FIG. At this time, the lifting device 4a releases the state in which the head of the bottle container is gripped by the workpiece gripping arm, and the bottle container is transferred onto the belt of the single-line conveyor 6a by the return operation of the push-out guide 7a. . After that, as shown in FIG. 7A, the guide member 8b hangs downward, and the lifting device 4a descends from the second height to the first height.

(Guide member 8b)
As shown in FIG. 7C, the guide member 8b rises upward to support the bottom of the bottle container raised (lifted) to the second height by the lifting device 4a, and the lifting device 4a In order to guide the conveyance direction (the course) of the bottle container to be raised, as shown in FIG. 7B, the operation of dropping downward is alternately repeated. According to the said structure, it can prevent that a container bottle remove | deviates from a course by guidance by the guide member 8b during conveyance by the lifting device 4a of the single row bottle container cut out. The guide member may be a rotary type, a slide type, or the like. For example, as shown in FIGS. 8 (f) and (g), a combination of a fixed guide member (guide member) 8c and a slide type bottle cradle 8d instead of the rotary guide member 8b. May be used.

(Extrusion guide 7a, suction part 7b)
As shown in FIGS. 7C and 7A, the push-out guide 7a is held by the guide member 8b after the bottle container is lifted by the lifting device 4a and reaches the second height. The bottle container is moved onto the belt of the single-line transport conveyor 6a while pushing the bottle container to the position where the suction part 7b comes into contact with the side surface of the bottle container released from the gripping arm and sucked by the suction part 7b. When it is pulled to the position where it is placed, the operation is repeated alternately. The extrusion guide 7a can be adjusted in the vertical direction according to the bottle size.

  The single-row transport conveyor 6a is substantially perpendicular to the transport direction of the multi-row transport conveyor 1a by rotating (running) the single-row bottle containers sent onto the belt by the pulling operation of the extrusion guide 7a. It is designed to be conveyed in the direction.

(About the operation | movement flow of the workpiece cutting device 20)
Next, the flow of the operation of the workpiece cutting device 20 described above will be described with reference to FIGS. First, as shown in FIG. 7 (a), the belt of the multi-line transport conveyor 1a on which the multi-line bottle containers are mounted rotates (runs), and the subsequent bottle containers are placed on the cradle of the bottle holding member 3a. With the force pushing the previous bottle container, the single row container bottles are fed until they come into contact with the upstream facing guide 2a.

  Next, after the heads of the single row bottle containers in contact with the upstream side opposing guide 2a are gripped by the work gripping arm of the lifting device 4a, as shown in FIG. Is conveyed (lifted) from the bottom to the top (from the first height to the second height).

  Next, as shown in FIG. 7C, the single row bottle containers are held by the guide member 8b, and the gripping by the work gripping arm of the lifting device 4a is released. Next, in a state where the side surface of the bottle container is sucked by the suction portion 7b, the bottle container is fed onto the belt of the single-line transport conveyor 6a by the pulling operation of the extrusion guide 7a as shown in FIG. It is. At this time, the rotation (operation) of the belt of the single row conveyor 6a is temporarily stopped to prevent the bottle containers from falling.

  Thereafter, after confirming the transfer of the single row bottle containers onto the belt of the single row conveyor 6a, the bottle containers are conveyed downstream by the rotation (operation) of the belt.

(Effect of the workpiece cutting device 20)
As described above, according to the workpiece cutting device 20, the lifting device 4a receives and receives the heads of the single row bottle containers with the workpiece gripping arms, and raises the received single row bottle containers. For this reason, the deterioration of the quality of the bottle container to convey can be suppressed compared with the structure which drops the bottle container disclosed by the said patent document 2 or 3 via a comparatively long drop chute or a downward passage.

  Moreover, according to the workpiece cutting device 20, the bottle holding member 3a grips the head of the single row bottle container by lowering the workpiece gripping arm of the lifting device 4a from the second height to the first height. The subsequent single row bottle container is temporarily held until the arm is gripped. For this reason, by appropriately adjusting the holding timing of the single row bottle containers by the bottle holding member 3a, the step of separating the multi row bottle containers and the step of supplying the single row bottle containers to the downstream side, Simultaneous operation is possible, and one-cycle operation time can be shortened to improve driving performance. Moreover, since the workpiece cutting device 20 has a simple configuration, the cost can be reduced as compared with the technique disclosed in Patent Document 1.

  As described above, according to the workpiece cutting device 20, it is possible to suppress the deterioration of the quality of the bottle container to be conveyed, reduce the cost, shorten the one-cycle operation time, and improve the driving ability.

  In addition, according to the workpiece cutting device 20, even in a high-capacity line, a multi-row bottle container can be made into a single row, and bottles can be supplied to the downstream machine without insufficient supply.

[How to detect the contact of the bottle container with the opposing guide]
Next, a method for detecting contact (or arrival) of the bottle container with respect to the upstream facing guide 2 (sensor for arrival confirmation) will be described. By arranging a light irradiation unit and a light receiving unit (not shown) at appropriate positions, as shown in FIG. 8, light is irradiated to one end A of the shoulder of the bottle container and propagates between the light irradiation unit and the light receiving unit. When is blocked, light reception by the light receiving unit is not performed, so that contact of the bottle container with the upstream facing guide 2 can be detected.

  Moreover, the detection method of contact | abutting with respect to the upstream opposing guide 2 of a bottle container is not limited to the method of using said light irradiation part and a light-receiving part. For example, as shown in FIG. 8, when a jig B is provided at an appropriate position near the upstream facing guide 2 and the bottle container abuts against the upstream facing guide 2, the jig B is indicated by an arrow. It is possible to detect the contact of the bottle container with respect to the upstream facing guide 2 by detecting the movement of the jig B. As described above, various methods can be used as a method of detecting contact of the bottle container with the upstream facing guide 2.

[How to prevent bottle containers from falling over (Part 1)]
Next, based on FIG. 9, a bottle container overturn prevention method (part 1) will be described. FIG. 9A and FIG. 9B are side views showing a method for preventing the bottle container from overturning with respect to the workpiece cutting device 10, respectively.

  As shown to (a) of FIG. 9, you may prevent a bottle container falling by providing the suction part 4b which attracts | sucks the bottom part of a bottle container on the base of the bottle raising / lowering stand 4 (vacuum system). Accordingly, the bottle container can be prevented from being overturned by the suction by the suction part 4b during the transport of the single row bottle container by the base of the bottle lifting platform 4.

  Further, as shown in the figure, in the vicinity of the terminal portion of the multi-row transport conveyor 1, the path of the single row of container bottles transported from the top to the bottom by the base of the bottle lifting platform 4 is guided, and the container bottles are You may provide the fall prevention guide (guide member) 8 which guides so that it may not fall down. Moreover, as a guide member, it is not limited to the fall prevention guide 8 mentioned above. For example, as shown in FIG. 9 (a), when the base of the bottle lifting platform 4 is completely lowered, it is lifted up and down, so that the single row of container bottles is removed from the course, and falls. You may provide the fall prevention plate 9 which prevents this. The rise of the fall prevention plate 9 prevents the container bottle from being removed from the course and falling. When the container bottle is pushed out by the push-out guide 5, the overturn prevention plate 9 is lowered so as not to hinder the pushing operation of the container bottle. Thereby, while the single row bottle container is being conveyed by the pedestal of the bottle lifting platform 4, the container bottle is prevented from coming off the course by the guide by the fall prevention guide 8 or the fall prevention plate 9, and the bottle container falls down. This can be prevented.

  Further, as shown in FIG. 9B, a fall prevention guide 8a in which the above-described fall prevention guide 8 is inclined by an angle θ (for example, about 5 °) can also be used. Due to the slight inclination of the overturn prevention guide 8a, the bottle container can be prevented from overturning while the single row bottle container is being conveyed by the base of the bottle lifting platform 4.

[About the fall prevention method for bottle containers (2)]
Next, based on FIG. 10, a bottle container overturn prevention method (part 2) will be described. FIG. 10 is a side view showing another method for preventing the bottle container from toppling over the workpiece cutting device 10. As shown in the figure, by providing an overturn prevention cylinder 12 that holds down one end of the shoulder of the subsequent container bottle before being transferred onto the base of the bottle lifting platform 4, the subsequent bottle container is prevented from falling over. Also good.
