Description

TECHNICAL FIELD The present invention relates to a device for removing foreign matter such as crowns and bottle fragments contained in a box that stores items such as bottles.

[Conventional technology]

Beer bottles and the like are usually stored in a box whose interior is partitioned such as a container for distribution, and empty bottles are also stored and collected in the same box. After the collection, the empty bottle is taken out of the box by the uncaster.

The uncaster has a large number of holders for holding the mouths of the bottles, and the holders hold the bottles, take them out of the box, and place them on the bottle conveyor.

However, the box containing the recovered empty bottles may contain foreign objects such as crowns that have come off the empty bottles and broken fragments of bottles. The uncaser removes empty bottles from the boxes that are placed on the conveyor and sequentially conveyed.
When the above foreign matter is sandwiched between the empty bottle and the partition of the box, the box may be lifted and the bottle cannot be pulled out from the box. In addition, the bottle may be taken out of the box with the foreign matter on its shoulder or the like and transferred onto the conveyor for transferring the bottle. In this case, the foreign matter will fall onto the conveyor for transferring the bottle. After that, when the next bottle is placed on the foreign matter that has fallen on this conveyor, the bottle will fall.

For this reason, conventionally, a person is placed in the middle of the conveyor, and before the empty bottle is taken out from the box by the anchor, foreign matters such as the crown and broken fragments of the bottle are manually removed from the inside of the box.

[Problems to be Solved by the Invention]

However, in the above-described conventional method for removing foreign matter,
There is a drawback that it is difficult to unmanned the entire line because it requires human intervention, and since the presence of foreign matter is confirmed by the human eye, the removal of foreign matter becomes uncertain.

The present invention has been made in order to solve the above-mentioned conventional problems. That is, the present invention provides an in-box foreign matter removing device capable of automatically and reliably removing foreign matter from the inside of a box in which items such as empty bottles are stored, and which is capable of unmanning the line. With the goal.

[Means for Solving the Problems]

The present invention, in order to solve the above problems, in a box foreign matter removing apparatus for removing foreign matter from the inside of the box in which the stored items are stored,
A conveyor that conveys the box is installed substantially horizontally,
A box stop member for stopping the conveyed box is provided in the middle of the conveyor so that the stored item take-out section for taking out the stored items stored in the box is located above the box stopped by the box stop member. The plurality of holders for detachably holding the stored items and the pitch of the holders are arranged at the pitch corresponding to the compartments in the box when the stored items are taken out of the box. The box is provided with a pitch changing mechanism for changing the pitch of the holder so that the pitch is larger than that, and the box is clamped at a position which is a side part of the conveyor and faces the box stopped by the box stop member. In addition, a box reversing unit that reverses the box after the stored items are taken out is installed.

[Action]

The box in which the items are stored in each section is conveyed on the conveyor and stopped at a predetermined position on the conveyor. Then, the box is clamped by the box inverting section.

Then, the holder part descends from the stopped box. At that time, the pitch between the holder parts is converted to the one corresponding to the compartment in the box by the operation of the pitch changing mechanism, and each holder part enters the box and holds the stored items.

After this, the holder part holds the stored item and ascends, and escapes to the outside of the box. At this time, since the box is clamped, the stored item can be reliably taken out of the box even if foreign matter is present between the stored item and the partition inside the box. Further, after the holder portion is raised, the pitch thereof is increased by the operation of the pitch changing mechanism. Therefore, when the stored items are, for example, beer bottles, foreign substances such as crowns on their shoulders fall. This falling object will be received by the box located below.

The box from which the stored items have been removed is reversed by the reversing device together with the clamp section. Therefore, foreign matters such as crowns and bottle fragments remaining in the box are removed to the outside of the box.

After this, the holder part descends toward the box, stores the stored items in the box, then rises again, and waits for supply of the next box.

The pantographs 23b and 23d are fixed such that one central axis of the pantographs 23b and 23d does not move with respect to the side surface cam plates 19b and 19d.

Therefore, the guide rods 20 other than the guide rod 20c at the center of the row are
When A, 20B, 20C, 20D, 20a, 20b, 20d, 20e move along the side cam plate, the matrix of the slider 24 also changes the pitch between the rows or columns accordingly, and the inside of the box 1 is changed. The pitch may correspond to each section of, or may be larger than that.

The pantographs 23a, 23b, 23c, 23d are the side cam plates 19a, 1
It may be provided inside 9b, 19c, 19d.

A fixed cam plate 25, which is a guide path member, is fixed to the upper part of the surface surrounded by the side surface cam plates 19a, 19b, 19c, 19d, and the four corners of the fixed cam plate 25 have rows and rows of both ends of the matrix. Cam groove 26 that is a guideway that extends in the direction that intersects both rows
Are formed respectively.

On the other hand, pins 27 are planted in the sliders 24 located at the four corners, and cam followers 28a and 28b are provided on each pin 27 one above and one below (FIG. 11). The lower cam follower 28b is engaged with the cam groove 26 of the fixed cam plate 25.

Therefore, when a force that moves along the cam groove 26 is applied to at least one slider 24, the sliders 24 have a pitch in the horizontal plane as shown in FIGS. 9 and 10. It will open and close while making changes.

In FIG. 6 to FIG. 8, the reference numeral 29 is for applying the above-mentioned force to the slider 24 and sliding the cam follower 28b as the guide along the cam groove 26 as the guide path. It is an air cylinder that is a drive unit.

The air cylinder 29 is arranged parallel to the matrix row of the guide rods in the center above the fixed cam plate 25,
The ends of the cylinder body and the rod 31 are connected to the two moving cam plates 30a and 30b arranged on the fixed cam plate 25 in parallel with the rows of the matrix.

On both sides of the movable cam plates 30a, 30b, elongated hole-shaped cam grooves 32 extending along the rows of the matrix are formed corresponding to the cam grooves 26 of the fixed cam plate 25, and these cam grooves 26 are formed. The upper cam follower 28a held by the pin 27 is engaged.

In addition, what is denoted by reference numeral 33 in FIGS. 7 and 8 is a slider fixed to the center of the lower surface of the moving cam plates 30a and 30b, and a guide plate 34 fixed to the upper surface of the fixed cam plate 25. You will be guided. Also,
Reference numeral 35 is a roller attached to both ends of the movable cam plates 30a and 30b, and is adapted to roll on the fixed cam plate 25. Reference numeral 36 indicates a stopper for surely stopping the moving cam plates 30a and 30b at proper positions.

As a result, air is supplied to the air cylinder 29, and when the rod 31 projects from the cylinder, the rod 31 and the moving cam plates 30a and 30b attached to the ends of the cylinder move so as to separate from each other. Then, fixed cam plate 25 on a plane
Of the diagonal cam groove 26 moves from the inner end to the outer end of the diagonal cam groove 26, and therefore the cam rollers 28a, 28 at the four corners of the matrix.
b moves from the inner end to the outer end of the cam groove 26, and the sliders 24a at the four corners integrated with this also move in the same manner. The movement of the sliders 24a at the four corners causes outward movement of the guide rods 20A, 20D, 20a, 20e at both ends of the row and column.
The guide rods 20A, 20D, 20a, 20e at both ends are the guide rods 20B, 20C, 20b, 20c, 20d in the middle portion and the pantographs 23a, 23b, 23c, 2
Since the guide rods 20c in the center of the row are fixed by the side cam plates 19b, 19d, the guide rods 20a, 20b, 20d, 20e in each row are centered on the guide rod 20c in the center of the row. Guide rods 20A, 20B, 20 of each row spread out on both sides at equal pitch
C and 20D will also spread to both sides at equal pitch. Thus,
Each slider 24 is a row and column guide rod 20A, 20B, 20C, 20D,
It slides along 20a, 20b, 20c, 20d, 20e and moves at equal pitches in both rows and columns. That is, the pitch of all the sliders 24 increases from the state shown in FIG. 9 to the state shown in FIG.

On the contrary, when the rod 31 retracts, all the sliders 24 move to the 10th position.
The state moves from the state shown in FIG. 9 to the state shown in FIG. 9 so that the pitch becomes smaller.

The holder portion 18 that detachably holds the beer bottle serving as the storage item 3 is attached to the lower portion of each slider 24.

The holder portion 18, as shown in FIGS. 11 to 14,
Below the slider 24, a gripper for gripping the bottle mouth.
It is configured by connecting 37 with a support rod 38.

The support rod 38 is formed by inserting a sliding rod 40 into a fixed rod 39 having a lateral hole 73 fixed to the slider 24 slidably in the vertical direction. To prevent separation, slide bar 40
The ring 41 attached to the upper end of the sliding rod 40 is engaged with the step inside the fixed rod 39 to prevent the sliding rod 40 from rotating around its axis.
Groove 42 extending in the axial direction and pin 43 inserted into the fixing rod 39
This is done by engaging with.

Reference numeral 44 is a compression coil spring interposed between the fixed rod 39 and the sliding rod 40, and the elasticity of the spring 44 causes the sliding rod 40 to be constantly urged downward.

Since the gripper 37 is elastically held together with the sliding rod 40 by the compression coil spring 44, if the bottle is lifted by the presence of foreign matter in the box and the bottle mouth 3a is raised, the sliding rod 40 Will rise. Then, the tip of the sliding rod 40 is caught by a photosensor (not shown) having an optical axis that passes through the lateral hole 73 of the fixed rod 39, and as a result, the entire apparatus stops.

The gripper 37 is provided with a bottomless rectangular frame 45 through which the bottle mouth portion 3a can come in and out, and an elastic member 46 that is in contact with the opening edge of the bottle mouth portion 3a is fixed to the ceiling portion thereof, and is slightly smaller than the bottle diameter. Two claw bodies 47a, 47b having a small cutout in the center are pivotally supported via a shaft 48 in a double door shape. Also, two claws 47
The a and 47b are connected to each other by a tension coil spring 49. Further, pins 50 are respectively arranged below the tip portions of the two claw bodies 47a, 47b, and both pins 50 are connected to a rod 53 of an air cylinder 52 via a support member 51. The air cylinder 52 is vertically fixed to the frame 45 of the grip 37.

As a result, when the pin 50 rises with the operation of the air cylinder 52, the pawls 47a, 47b are pushed open so as to rotate upward. Further, when the pin 50 is lowered by the reverse operation of the air cylinder 52, the claw bodies 47a and 47b are closed due to the contraction of the tension / compression coil spring 49. On the other hand,
When the movable frame 17 descends and the claw bodies 47a, 47b receive a force upward in the bottle mouth portion 3a, they are pushed open regardless of the operation of the air cylinder 52.

A rectangular movable frame 17 that supports the holder 18 and the like.
Is connected to the upper end of a rod 55 of an air cylinder 54 installed in the central portion of the gate-shaped frame 16, as shown in FIGS.

Therefore, the air cylinder 54 raises or lowers the movable frame 17 along the gate-shaped frame 16 and causes the gripper 37 of the holder portion 18 to enter the box 1 on the conveyor 2 and then the first frame.
It functions to pull up to the position indicated by the solid line in FIGS.

A bracket 57 protruding above the conveyor 2 is fixed to the gate-shaped frame 16, and a foreign matter diffusion prevention is urged by a torsion spring so as to enter the movement path of the movable frame 17 on the bracket 57. A plate 58 is attached.

The foreign matter diffusion prevention plate 58 comes into contact with the bracket 56 of the movable frame 17 and is rotated downward due to the lowering of the movable frame 17 due to the driving of the air cylinder 54, and the holder portion 18 is held in the bottle in the box 1. Hold and hold that posture until you rise. Then, when the movable frame 17 rises and separates from the foreign matter diffusion prevention plate 58, the foreign matter diffusion prevention plate 58 returns to the original position.

The box reversing section 5 is provided in FIGS. 1 to 5 and 15 to 17.
As shown in the figure, it is installed in the vicinity of the box stop position of the conveyor 2 and at a position facing the gate frame 16.

The box reversing unit 5 includes a clamp mechanism for clamping the box 1 stopped on the conveyor 2, and a reversing device including a rotating shaft 59 for reversing the clamp mechanism together with the box 1 held by the clamping mechanism.

The rotating shaft 59 is attached to the lower frame 9 of the in-box foreign matter removing device in parallel with the traveling direction of the conveyor 2, and has a shaft end at which a deceleration for rotating the rotating shaft. Motorized motor 60 is arranged.

The clamp mechanism is fixed to the rotary shaft 59 and
It has two vertical frames 61 extending in a direction perpendicular to 59. A horizontal bracket 62 is spanned between the vertical frames 61, the stopper 70 is attached to the horizontal bracket 62, and a guide rod 63 extending in the vertical direction is provided.
Is fixed.

Air cylinders 64 and 65 are provided above and below the horizontal bracket 62, respectively.
Is fixed. Then, plate-shaped clamp members 67 and 68 extending in the horizontal direction are fixed to the tips of the rods 66 of the air cylinders 64 and 65, respectively. The guide rod 63 is slidably inserted into each of the clamp members 67 and 68.

As a result, when the upper and lower air cylinders 64, 65 are operated to bring the clamp members 67, 68 closer to each other, the upper and lower surfaces of the side wall of the clamp mechanism of the box 1 on the conveyor 2 are gripped by the clamp members 67, 68. . As a result, the box 1 floats on the conveyor 2. Then, when the rotating shaft 59 rotates, the box 1 is reversed to the position indicated by the one-dot chain line in FIG. 1 while being held by the clamp mechanism. For this reason, Box 1
The foreign matter inside will be removed to the outside of the box 1. However, at that time, the stored beer bottle contents 3 have already been taken out of the box 1 by the take-out unit 4.

A reference numeral 69 in FIG. 4 is a safety frame that prevents a person or the like from entering the range in which the clamp mechanism or the like rotates.

Next, the operation of the box foreign matter removing device will be described.

When the box 1 in which the storage items 3 such as empty beer bottles are stored is conveyed on the conveyor 2 and reaches the position directly below the storage item take-out section 4, the upstream and downstream stoppers 10a and 10b are located above the upper surface of the conveyor 2. Also protrudes upward, the downstream side stopper 10b stops the box 1, and the upstream side stopper 10a prevents the subsequent box from entering.

Then, the side pushing member 14 is actuated to move the box 1 to the side pushing member.
The box 1 is pressed against the stopper 70 opposed to 14 to properly position the box 1. Then, the positioned box 1 is clamped by operating the clamp members 67 and 68 of the clamp mechanism.

Next, the movable frame 17 is lowered toward the box 1 by the operation of the air cylinder 54 of the stored-item take-out section 4, and its holder section is moved.
The gripper 37 of 18 comes into contact with the bottle mouth portion 3a. Then, due to the contact pressure, the two claw bodies 47a, 47b spread upward and the claw bodies 47a, 47b are expanded.
The bottle mouth 3a enters between the tips of 7b, and
As shown in the figure, the constricted portion of the bottle mouth portion 3a engages with the claw bodies 47a, 47b.

Thereafter, the air cylinder 54 operates in the opposite direction to raise the movable frame 17, and the empty bottle is taken out of the box 1.

Then, when the bracket 56 of the movable frame 17 passes through the contact point with the foreign substance diffusion prevention plate 58, the air cylinder 29 of the pitch changing mechanism is actuated to change the pitch of the holder portion 18 from the state shown in FIG. 9 to the state shown in FIG. Change to the state of.

As a result, foreign matter such as dust sandwiched between the bottles or riding on the shoulders of the bottles falls. At this time, the foreign matter diffusion prevention plate
Since 58 is in the state as shown in FIG. 2, it guides falling dust and the like to the inside of the box 1.

In this way, when the empty bottle is taken out of the box 1 and foreign matter is removed from the bottle, the rotating shaft 59 of the box reversing unit 5 rotates to invert the box 1 together with the clamping mechanism. Therefore, the foreign matter in the box 1 is removed to the outside of the box 1.

Thereafter, the rotating shaft 59 rotates in the opposite direction to the above, the empty box 1 is returned to its original position, and the clamp mechanism releases the empty box 1 onto the conveyor 2.

Further, by the operation of the air cylinder 54 of the stored-material take-out portion 4, the holder portion 18 holding the empty bottle descends toward the box 1, and the empty bottle is stored in the box 1 again.

At this time, the holder portion 18 is already in the state shown in FIG. 9 by the operation of the air cylinder 29 of the pitch changing mechanism.

When the holder 18 stores the empty bottle in the box 1, each holder 18
Each air cylinder 52 of the
50 is lifted to disengage the claw bodies 47a, 47b from the constricted portion of the bottle mouth portion 3a, and the bottle serving as the storage item 3 is released from the holder portion 18.

After this, the movable frame 17 again rises to the position shown in FIGS. 1 and 2, and stands by for foreign matter removal processing of the next box.

On the other hand, the clamp members 67 and 68 release the box 1. And
The upstream and downstream stoppers 10a and 10b descend, the foreign matter-removed box 4 in which the stored items are stored again flows on the conveyor 2 to the downstream side, and an unprocessed box arrives again. It is stopped by the protruding downstream side stopper 10b and is used for the foreign matter removing process.

〔The invention's effect〕

As described above, the apparatus for removing foreign matter in a box according to the present invention clamps the box containing the items conveyed by the conveyor to temporarily take out the items from the inside of the box, and then reverses the box to remove the foreign substances. Since it is made to fall from the inside of the box, the foreign matter in the box can be automatically and surely removed. Even if a foreign object is caught between the partition inside the box and the stored item when the stored item is taken out upward from the box, the box is lifted because the box is clamped and the stored item cannot be taken out. There is no danger, and since the space between the stored items taken out from the box is widened, the foreign substances taken out from the box together with the stored items do not fall into the box again and scatter around. , The foreign matter is removed from the inside of the box by reversing the box.

If the in-box foreign matter removing device according to the present invention is installed on the upstream side of the answerer, the line can be unmanned.
