Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a boxing device provided with a configuration in which a plurality of products having a rectangular parallelepiped shape such as a gum product are arranged in a horizontal row in a contact state, sucked and conveyed, and boxed.
[0002]
[Prior art]
FIG. 8 is a schematic view showing a conventional gum product boxing apparatus.
Conventionally, as shown in the figure, this type of boxing apparatus extrudes a gum product 1 that has been conveyed to an extrusion position 201 by a supply conveyor 200 to a side by a pusher 202 by a predetermined number, and an elevator 203 It has a mechanism that is placed on a lifting platform. The elevator 203 pushes up the gum products 1 arranged in a horizontal row into the packaging box 2. The pushed-up gum product 1 is held by latch claws (not shown), and this is repeated a predetermined number of times to carry out a predetermined number of boxes, and the turret 204 rotates to complete the packing. The packaging box 2 is conveyed to a position above the elevator 203 by a turret 204 that is intermittently rotated.
[0003]
The packaging box 2 containing the gum product 1 is conveyed to the discharge position by intermittent rotation of the turret 204 and is delivered to the discharge conveyor 206 by the pusher 205.

[0005]
[Problems to be solved by the invention]
The above-described conventional boxing apparatus is configured to push the gum products 1 arranged in a horizontal row onto the upper surface of the elevator 203 by the pusher 202. At this time, the gum products 1 are received with the supply conveyor 200 on the delivery side. Even if there is a slight vertical displacement between the side elevator 203 and the elevator 203 on the side, there is a risk that the gum product 1 will be caught by the step and displaced. In addition, the gum product 1 stacked on the upper surface of the elevator 203 may be displaced due to shaking or vibration caused by the up-and-down movement of the elevator 203, resulting in lack of operational stability.
[0006]
If the position of the gum products 1 arranged in a horizontal line is slightly shifted, the proper storage in the packaging box 2 cannot be performed, and the gum product 1 and the packaging box 2 that cannot be stored manually by the workers one by one. Since it had to be removed, it had the problem that work efficiency was bad.
[0007]
The present invention has been made in view of such circumstances, and a plurality of rectangular parallelepiped products can be stably transported by arranging them in a horizontal row in a contact state, and can be properly stored in a packaging box. The purpose is to provide a boxing device that can be used.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the boxing device of the present invention includes a product supply means for arranging a plurality of products having a rectangular parallelepiped shape in a horizontal row in a contact state and arranging them in a predetermined product supply position, and is fixed to the side of the supply position. The product storage position is provided in a product packaging line including a product storage position provided with a space between the product storage position and a packaging box transporting means for placing a packaging box having an upper surface opened to the product storage position. A boxing device that adsorbs a plurality of products arranged in a line and inserts them into a packaging box arranged at a product storage position from above, and has the following configuration.
[0009]
(A) Power shaft that is supported to be freely rotatable and movable up and down.
(B) Rotation drive means for rotating the power shaft by a predetermined angle
(C) Elevating means for elevating and lowering the power shaft
(D) A support arm that is fixed to the power shaft, rotates integrally with the power shaft, and moves up and down, and extends to both sides around the power shaft, and has bearings at both ends.
(E) Support rod supported by each bearing portion of the support arm
(F) Product adsorption unit mounted on the lower end of each of these support rods
[0010]
Furthermore, the product suction unit includes a plurality of suction heads for individually suctioning the upper surfaces of a plurality of products arranged in a horizontal row in contact with the product supply position;
A flat plate-shaped protective member provided around the suction heads and in contact with the upper surfaces of a plurality of products sucked by the suction heads.
[0011]
The boxing device of the present invention having the above-described configuration sucks and conveys a plurality of products by each suction head, so that there is less possibility that the product will be displaced during transportation compared to the push-and-feed transportation using a pusher as in the prior art. . In addition, a flat plate-shaped protective member is provided around each suction head, and the protective member contacts the upper surface of a plurality of products to be sucked and conveyed, and supports the upper surface of the product and moves in the air. There is no guide contact, and movement due to inertial force or centrifugal force that occurs during airborne transfer can be prevented, so that the product is less likely to be displaced.
[0012]
In addition, the boxing device of the present invention is configured to insert a plurality of products sucked by each suction head into the packaging box from above, but the product in the process of this insertion operation due to deformation of the packaging box or the like. Is likely to come into contact with the inner peripheral surface of the packaging box. However, according to the present invention, since the upper surface of the plurality of products is supported by the protective member, even if the product comes into contact with the packaging box in such an operation process, it can be properly stored without causing displacement. It is.
[0013]
As a conventional apparatus capable of simultaneously sucking a plurality of products, a suction head disclosed in Patent Document 1 is known. However, the suction head of Patent Document 1 does not have a configuration corresponding to the protective member of the present invention, and therefore cannot expect the operational effects of the present invention.
[0014]
The suction head can be configured to have an elastic suction member in which the hollow portion is vacuum-sucked. In this adsorption member, the adsorption surface protrudes downward from the lower surface of the protection member, and when the upper surface of the product is adsorbed, the adsorption member contracts with the suction pressure in the hollow portion and lifts the adsorbed product upward.
If comprised in this way, a protection member does not become a hindrance, but the adsorption surface of an adsorption member can contact a product reliably, and can adsorb the product. And after adsorb | sucking a product, since an adsorption | suction member shrinks and lifts a product, the upper surface of a product contacts a protection member reliably by this.
[0015]
Moreover, it is preferable that the lower surface of the protection member has a configuration that substantially corresponds to the outer peripheral edge of the upper surface of a plurality of products arranged in a horizontal row in contact. As a result, the contact area with a plurality of products is increased, and it is possible to more reliably support the products and prevent displacement.
[0016]
The product adsorption unit may include a unit main body block that is attached to each lower end of each support rod, and an impact buffer member that is movably incorporated in the unit main body block.
In this case, the suction head and the protection member are supported by the shock absorbing member, and are configured to be movable integrally with the shock absorbing member with respect to the unit body block.
If comprised in this way, when a product, a suction head, a protection member, etc. collide with some obstacle in the middle of carrying out suction conveyance of a plurality of products, for example, a product suction unit rotating with a power axis, an impact buffering member will be It can move and buffer the impact caused by the collision, and protect the collided products and members.
[0017]
Further, when the shock absorbing member moves relative to the unit main body block with respect to the product suction unit, a collision detection sensor that detects this movement can be used to quickly detect the occurrence of the problem due to the collision, and Operation control such as emergency stop can be executed.
[0018]
In addition, if a plurality of suction heads are provided with suction confirmation sensors that individually detect the presence or absence of product suction, the reliability of the boxing operation is increased without causing a shortage of stored products due to suction mistakes or the like. With this suction confirmation sensor, it is possible to quickly detect the dropout of the product during the suction conveyance.
[0019]
The support rod may be configured to be supported by each bearing portion of the support arm so as to be movable up and down. When comprised in this way, a support rod is always put in the downward movement end with the dead weight containing a product adsorption | suction unit. When the product suction unit descends and comes into contact with the product, the support rod rises relative to the support arm that further descends. Therefore, there is no possibility that an excessive load is applied to the product adsorption unit or the product to be adsorbed.
[0020]
The elevating means has a disk-shaped partition wall formed facing the upper and lower sides at a certain interval, a connecting member provided at the lower end of the power shaft, a link member swingable with the intermediate portion as a fulcrum, A roller member provided at one end of the link member and disposed between the partition walls of the connecting member, a cam follower provided at the other end of the link member, a slider that reciprocates horizontally, and a servo motor that reciprocates the slider. And a cam groove that is formed on the slider and engages with a cam follower to convert the reciprocating movement of the slider into a swinging motion of the link member.
[0021]
In this case, if a counter for counting the reciprocating drive of the slider by the servo motor is provided, the product storage stage in the packaging box can be counted reliably.
[0022]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a product packaging line in which a boxing apparatus according to this embodiment is incorporated. This embodiment has shown the structural example of the apparatus which makes several gum products 1 the object product (product which carried out the rectangular parallelepiped shape), and packs this.
[0023]
As shown in FIG. 1, the product packaging line includes a product supply conveyor 101 (product supply means) that arranges a plurality of gum products 1 in a horizontal row in a contact state and arranges them at a product supply position 100, and a side of the product supply position 100. A packaging box arrangement table 102 provided at a predetermined interval, a packaging box conveyor 103 (packaging box conveyance means) for arranging the packaging box 2 having an upper surface opened to the packaging box arrangement table 102, and a packaging box arrangement A discharge conveyor 104 for carrying the packaging box 2 in which the gum product 1 is stored on the table 102 to the downstream side. The installation position of the packaging box arrangement table 102 corresponds to the product storage position.
The boxing device is installed in a space between the product supply conveyor 101 and the packaging box placement table 102 (product storage position).
[0024]
The product supply conveyor 101 conveys the gum products 1 in a contact state (pressed and pressed state), and arranges a predetermined number of gum products 1 in a horizontal row at the product supply position 100. A product stopper 105 is provided on the downstream side of the product supply position 100, and the gum product 1 that has been conveyed is blocked by the product stopper 105 and stops at the product supply position 100.
The boxing device sucks and conveys a plurality of gum products 1 arranged in a horizontal row in contact with the product supply position 100 and inserts them from above into the packaging box 2 arranged on the packaging box arrangement table 102.
The packaging box 2 is supplied to the upper surface of the packaging box transport conveyor 103 from a box supply device (not shown). The packaging box 2 is stocked in a folded state. A box supply device (not shown) is expanded and formed into a box shape with an upper surface opened, and then placed on the upper surface of the packaging box conveyor 103.
In the packaging box 2, the gum products 1 arranged in a horizontal row are stacked and stored in a predetermined number of stages. The discharge conveyor 104 carries out the packaging box 2 downstream after the sliding operation of the gum product 1 is finished.
[0025]
2 is a front sectional view showing the overall structure of the boxing device according to the present embodiment, FIG. 3 is a perspective view showing the upper structure of the device, and FIG. 4 is an exploded perspective view for explaining the lifting mechanism of the device. .
[0026]
As shown in FIG. 2, the boxing device is configured around a power shaft 12 supported by a device body 10 via a bearing 11. The power shaft 12 is supported so as to be rotatable and movable up and down, and a timing pulley 13 is mounted near the lower end. A timing belt (not shown) is wound around the timing pulley 13, and a rotational driving force from a rotation driving motor (rotation driving means) (not shown) is transmitted through the timing belt. The power shaft 12 rotates by a predetermined angle rotation (in this embodiment, reciprocal rotation of 180 °) with this rotational driving force.
[0027]
An elevating mechanism 14 (elevating means) that elevates and lowers the power shaft 12 is disposed at the bottom of the apparatus body 10. The elevating mechanism 14 operates using a driving robot 16 that reciprocates the slider 15 in the horizontal direction by a built-in servo motor as a driving source.
[0028]
As shown in FIG. 4, the slider 15 is formed with a cam groove 17 extending in the vertical direction. On the other hand, the apparatus main body 10 is provided with a swingable link member 19 with an intermediate portion as a fulcrum 18. A cam follower 20 is attached to one end of the link member 19, and a roller member 21 is attached to the other end. A cam follower 20 attached to the link member 19 is engaged with the cam groove 17 of the slider 15.
[0029]
Further, a connecting member 22 is attached to the lower end of the power shaft 12 (see FIG. 2). As shown in FIG. 4, the connecting member 22 has a disk-shaped partition wall 23 formed to be opposed to each other at a certain interval, and the link member 19 is interposed between the disk-shaped partition walls 23. The roller member 21 attached to the is inserted and arranged.
[0030]
With this configuration, when the slider 15 reciprocates in the horizontal direction, the cam follower 20 moves relative to the vertical direction along the cam groove 17, and the link member 19 swings around the fulcrum 18. Along with this swinging, the roller member 21 pushes up the partition wall 23 of the connecting member 22 upward or downward to raise or lower the power shaft 12.
At this time, since the link member 19 swings according to the lever principle, the distance from the fulcrum 18 to the cam follower 20 is set to be longer than the distance from the fulcrum 18 to the roller member 21, thereby reducing the size and power of the link member 19. Even if a servo motor is used, it is possible to obtain a large driving force for moving the heavy power shaft 12 up and down.
Further, when the power shaft 12 rotates, the roller member 21 rolls between the disk-shaped partition walls 23, so that the rotating operation is not hindered.
[0031]
As shown in FIGS. 2 and 3, a support arm 30 is fixed to the power shaft 12 at an upper portion thereof. The support arm 30 rotates integrally with the power shaft 12 and moves up and down. The support arm 30 extends to both sides around the power shaft 12, and bearing portions 31 are formed at both side ends. Each bearing 31 supports the support rod 32 so as to be movable in the vertical direction (axial direction).
[0032]
A timing pulley 33 is attached to the upper end of each support rod 32, while a timing pulley 34 is also attached to the upper end of the power shaft 12. A timing belt 35 is wound around these timing pulleys 33 and 34. When the power shaft 12 rotates, the rotation is transmitted to each support rod 32 via the timing belt 35, and each support rod 32 rotates. To do. That is, the support rod 32 revolves around the power shaft 12 integrally with the power shaft 12 and rotates around its own shaft center.
[0033]
The timing pulley 33 attached to each support rod 32 is rotatably held by the bearing portion 31 of the support arm 30, and is attached to the support rod 32 via a key groove and a key engaged therewith. ing. As a result, the support rod 32 is secured to move freely in the axial direction. A product suction unit 40 is attached to the lower end of each support rod 32.
[0034]
5 is a front view of the product adsorption unit, FIG. 6 is an enlarged side view of the same, and FIG. 7 is a plan view of a holding member provided in the unit.
The product suction unit 40 includes a unit main body block 41, an impact buffer member 42, a head support plate 43, a plurality of suction heads 44, and a flat plate-shaped protection member 45.
[0035]
As shown in FIG. 5, the unit body block 41 is fastened to the lower end of the support rod 32 with a fastener 46 such as a bolt. Here, by adjusting the fastening force, when an external force is applied to the unit main body block 41, the block 41 can be rotated to escape from the external force.
Inside the unit body block 41, a guide groove 47 having an arcuate inner peripheral surface and extending in the lateral direction is formed. The guide groove 47 has an open bottom surface. The shock absorbing member 42 is formed with a slide portion 42a that engages with the guide groove 47 at the top, and a support block portion 42b that hangs downward from the slide portion 42a. A flat head support plate 43 is attached to the lower end of the support block 42b with a fastener 48 such as a bolt.
[0036]
A stopper groove 42c is formed on the peripheral surface of the slide portion 42a of the shock absorbing member 42 at regular intervals (see FIG. 6). From the side surface of the unit main body block 41, an insertion hole for the lock pin 49 is formed toward the guide groove 47, and the lock pin 49 is screwed into the insertion hole. At the tip of the lock pin 49, there is provided a spherical engagement piece 50 that is urged and protruded by a built-in spring member (not shown), and this engagement piece 50 engages with the stopper groove 42c. The free movement of the shock absorbing member 42 is restricted.
[0037]
When an external force in the sliding direction is applied to the impact buffer member 42 and the members (the head support plate 43, the suction head 44, the protection member 45) and the like attached thereto, the engagement piece 50 provided at the distal end of the lock pin 49 has its external force. Retreats to the inside of the lock pin 49 without resisting. Then, the shock absorbing member 42 slides along the guide groove 47. Thereby, the shock received by the shock buffering member 42 is buffered, and the shock buffering member 42 and the members (the head support plate 43, the suction head 44, the protection member 45, etc.) attached thereto can be protected from external force.
[0038]
Further, as shown in FIG. 5, the unit body block 41 is provided with an impact detection sensor 51 including a proximity sensor or the like, while the impact buffer member 42 is provided with a proximity plate 52. The proximity plate 52 is disposed close to the impact detection sensor 51 in a normal state, and is separated from the sensor 51 when the impact buffer member 42 slides. The impact detection sensor 51 detects the separation of the proximity plate 52 and outputs an abnormal signal indicating that the impact buffering member 42 or the like has collided with something.
[0039]
A plurality of suction heads 44 are mounted side by side on the head support plate 43. In the present embodiment, as shown in FIG. 7, the suction head 44 is provided with a pair of front and rear groups arranged in five rows in the horizontal direction, and the suction heads 44 in each row individually suck the gum product 1.
[0040]
Each suction head 44 has a suction member 54 at the lower end of the shaft 53, and is fixed to the head support plate 43 in such a posture that the shaft 53 hangs down with a fastener 55 such as a nut. The adsorbing member 54 is made of a resilient member such as synthetic rubber, and has a thin umbrella shape with a hollow inside and an open lower end surface. The lower end surface is an adsorption surface 54a, and a fold 54b that expands and contracts in a bellows manner is formed in the vicinity thereof. The inside of the hollow portion of the suction member 54 is vacuum-sucked by the vacuum suction unit 56 shown in FIG. 1 through a suction pipe (not shown). And the gum product 1 is adsorbed on the adsorption surface 54a with the suction force.
[0041]
The vacuum suction unit 56 shown in FIG. 1 vacuums the suction members 54 of the suction heads 44 individually. The vacuum suction unit 56 is provided with suction confirmation sensors 57 that individually detect the presence or absence of product suction for the plurality of suction heads 44. When any of the suction heads 44 does not suck the gum product 1 or when the gum product 1 is dropped off in the middle, the suction pressure with respect to the suction head 44 decreases. When the suction confirmation sensor 57 detects a decrease in the suction pressure, the suction confirmation sensor 57 outputs an abnormal signal indicating that the suction head 44 is not sucking the product.
[0042]
When the gum product 1 is adsorbed on the adsorption surface 54a of the adsorption member 54, the suction pressure in the hollow portion increases. In response to this suction pressure, the folding member 54b of the suction member 54 contracts and lifts the suction surface 54a upward.
[0043]
Further, the support shaft 59 is fixed to the head support plate 43 with a fastener 58 such as a nut so as to hang downward, and a protection member 45 is fixed to the lower end of the support shaft 59. The protection member 45 has a flat plate shape, and is horizontally disposed around each adsorption member 54. That is, as shown in FIG. 7, the protection member 45 has a notch 45a formed at a location corresponding to each suction member 54, and the suction member 54 is disposed through the notch 45a.
[0044]
Here, the suction surface 54a of the suction member 54 is always positioned so as to protrude downward from the lower surface of the protection member 45 (see FIG. 6). The protrusion dimension d can be arbitrarily set within a range shorter than the length by which the suction surface 54a is lifted when the rubber product is sucked. In general, the suction surface 54a of the suction member 54 only needs to protrude slightly downward from the lower surface of the protection member 45. For example, a protrusion size of about 1 mm to several mm is sufficient.
[0045]
By setting in this way, the suction surface 54 a protruding downward from the lower surface of the protective member 45 can reliably contact the gum product 1. Moreover, after the suction, the suction member 54 contracts due to the suction force in the hollow portion, and the gum product 1 is lifted and brought into surface contact with the lower surface of the protection member 45. Thereby, the upper surface of the gum product 1 is supported by the protective member 45.
[0046]
The lower surface of the protective member 45 is formed in an outer shape that substantially corresponds to the outer peripheral edge of the upper surface of the plurality of gum products 1 that are adsorbed by the respective adsorption heads 44 (see FIG. 7). By doing in this way, the contact area to the several gum product 1 becomes large, and it becomes possible to support the gum product 1 more reliably and to prevent position shift.
[0047]
The aforementioned boxing device is controlled by the control device 60 shown in FIG. The control device 60 has a built-in counter that counts the reciprocating movement of the slider 15 in the driving robot 16 shown in FIG. 2, and counts the lifting and lowering operation of the power shaft 12 using the counter.
[0048]
The power shaft 12 is in the raised position in the initial state, and one of the product suction units 40 is disposed above the product supply position 100 and the other is disposed above the packaging box placement table 102. Then, when a predetermined number (five in this embodiment) of gum products 1 are arranged in a horizontal row in a contact state at the product supply position 100, and the packaging box 2 is further disposed on the packaging box placement table 102, The control device 60 operates the driving robot 16 to move the slider 15 horizontally (forward movement) in one direction. As the slider 15 moves horizontally, the power shaft 12 descends, and each suction member 54 in one product suction unit 40 contacts the upper surface of each gum product 1 at the product supply position 100. At this time, the control device 60 controls the vacuum suction unit 56 corresponding to the suction members 54 to suck the vacuum inside the hollow portion of the suction member 54 and suck the gum product 1 on the suction surface 54a.
[0049]
Subsequently, the control device 60 operates the driving robot 16 to horizontally move (return) the slider 15 in the other direction. As the slider 15 moves horizontally, the power shaft 12 rises and each product suction unit 40 also rises. At this time, the control device 60 adds one to the counter value. Further, the control device 60 operates a rotary drive motor (not shown) to rotate the power shaft 12 by 180 °. Along with this rotation, the support arm 30 is also rotated by 180 °, and the support rods 32 mounted on both side ends revolve around the power shaft 12, and the support rod 32 rotates by 180 °.
[0050]
The plurality of gum products 1 adsorbed by one product adsorption unit 40 are positioned above the packaging box 2 by the ascending operation and the rotating operation. The other product supply unit is disposed above the product supply position 100. At the product supply position 100, the product supply conveyor 101 is operated in parallel with the operation of the boxing device, and a predetermined number (in this embodiment, five) of gum products 1 are arranged in a row in a contact state in advance. .
[0051]
Next, the control device 60 operates the driving robot 16 to move the slider 15 horizontally (forward movement) in one direction. As the slider 15 moves horizontally, the power shaft 12 descends again, and one of the product suction units 40 inserts the sucked gum product 1 into the packaging box 2 from above. At this time, even if the packaging box 2 is slightly deformed, the gum product 1 contacts the inner peripheral surface of the packaging box 2 and the like. However, since the upper surface of the gum product 1 is supported by the protective member 45, the gum product 1 is stored in the packaging box 2 without being displaced even if it contacts the packaging box 2 during the lowering.
[0052]
When the gum product 1 is adsorbed by the packaging box 2, the vacuum suction unit 56 corresponding to the adsorbing member 54 adsorbing the gum product 1 is controlled to destroy the adsorbed state. On the other hand, with respect to the other product suction unit 40 that has been lowered at the product supply position 100 and has come into contact with the gum product 1, the control device 60 controls the corresponding vacuum suction unit 56, so The inside of the hollow part 54 is vacuum-sucked, and the gum product 1 is adsorbed on the adsorption surface 54a.
[0053]
The above operation is repeated, and when the count value of the counter reaches the specified number of storage stages of the gum product 1 in the packaging box 2, the discharge conveyor 104 is operated to discharge the packaging box 2. During the operation, when the control device 60 inputs an abnormal signal from the impact detection sensor 51 provided in the product suction unit 40, the control device 60 immediately stops the product packaging line. Similarly, when the control device 60 inputs an abnormal signal from the suction confirmation sensor 57 provided in the vacuum suction unit 56, the control device 60 immediately stops the product packaging line. Thereby, while avoiding damage to a component, discharge | emission of a defective boxed product can also be prevented.
[0054]
In addition, this invention is not limited to embodiment mentioned above, For example, it can apply besides the boxing of the gum product 1.
[0055]
【The invention's effect】
As described above, according to the present invention, a plurality of rectangular parallelepiped products can be stably conveyed while being arranged in a horizontal row in a contact state, and can be properly stored in a packaging box.
