Description

The present invention relates to a cap reversing device.

  When an article such as a cap is supplied to the article processing apparatus, an article inversion apparatus that inverts and supplies the article may be used. For example, when the cap aligned by the aligner is to be supplied to the cap tightening machine, the cap aligned by the aligner is aligned with the center of gravity side, that is, the top surface of the cap downward. However, in the cap tightening machine, the cap cannot be tightened into the container unless the cap is gripped with the top surface facing upward. Therefore, an article reversing device that flips the caps up and down 180 degrees is required between the aligning machine and the cap tightening machine.

Conventionally, there exists a thing of patent documents 1-3 as an article inversion device.
The article reversing device described in Patent Document 1 reverses an article in a conveying process in which the article slides down due to gravity. An upper inlet part of a semicircular upside down chute is connected to a first belt conveyor that conveys articles aligned by an aligner, and a second belt conveyor is connected to a lower outlet part of a semicircular upside down chute It is. Articles carried in by the first belt conveyor are turned upside down by a semicircular upside down chute, and the reversed articles are carried out by the second belt conveyor.

  As another article reversing device, there is also an apparatus for turning the article upside down through an upside down chute twisted like a screw with respect to the article traveling direction while sliding the article down with an obliquely downward chute.

  The article reversing device described in Patent Document 2 stores a certain number of articles in the reversing device and then reverses the articles. A certain number of articles aligned by the aligning machine are received by the article receiving unit, and the article receiving unit is rotated 180 degrees by the turning actuator, whereby the articles are turned upside down and discharged.

  The article reversing device described in Patent Document 3 reverses an article in an aligner. In the article conveying apparatus in which a plurality of fixed floors and moving floors are alternately arranged, the floor surface of the floor height fixed floor disposed on the most downstream side is made higher than the floor surfaces of the other fixed floors, The floor surface of the steeply inclined moving floor disposed downstream is steeper than the floor surface of the other moving floors.

  In the prior art, when an article is turned upside down by an upside down chute, a drop and a distance necessary for the turning are necessary, and there are cases where the conveying direction is restricted. Moreover, the combined use property for the article shape and size is low. In Patent Document 1, a space for installing a semicircular upside down chute is required. Since the conveyance direction is also reversed at the entrance and exit, there are restrictions from the standpoint of apparatus installation. Also, when the shape or size of the article is changed, a semi-circular upside down chute remodeling part is required, but generally this semicircular upside down chute needs to be machined and tends to be expensive. . The same problem arises when the upside down chute is twisted like a screw with respect to the traveling direction. In particular, since the shape of the reversing part of the upside down chute that is twisted into a screw shape is complicated, time and labor are required for fine adjustment to prevent the article from becoming boring.

  In addition, a product in which a certain number of articles are stored in the article receiving unit and then reversed by an actuator requires a drop and a distance necessary for the reversal, which may restrict the conveyance direction. Moreover, the combined use with respect to an article shape and size is also low. Since Patent Document 2 requires an article receiving unit that receives a plurality of articles, a large installation space is required. Installation space for the actuator for reversing is also required. Since the input direction and the discharge direction of the article to the article receiving unit are reversed, there are restrictions from the viewpoint of apparatus installation. Further, when the shape or size of the article is changed, the article receiving part needs a remodeling part, but the article receiving part tends to be expensive because of its complicated structure.

  In addition, when an article is reversed in an aligner, the structure and control of the aligner tend to be complicated, and there are certain restrictions on the compatibility of the article shape and size. Since Patent Document 3 requires two steps in which the top surface side of an article is first directed upstream in a fixed floor height and the top surface side is directed upward in a steeply inclined moving floor, it takes time to design and adjust the apparatus. In addition, for articles such as jar caps whose cap diameter is considerably larger than the cap height, it is difficult to push up the center of gravity of the cap with the moving floor upstream of the fixed floor height, and the top surface of the cap may be directed upstream. As a result, it is difficult to align the direction by upside down.

  It is an object of the present invention to minimize the installation space of equipment necessary for flipping an article upside down, and to reverse various articles upside down with a simple configuration without making the transport direction before and after the article is reversed.

The invention according to claim 1 is a cap reversing device that has a top surface and a bottom surface, and reverses the cap with the bottom surface being pierced while transporting the cap , and the vertical moving floor and the outlet side fixed floor are arranged along the transport direction of the cap. Te disposed, vertically moving bed has a floor lift forms a descending slope toward the downstream side in the transport direction of the cap, and a vertical wall erected by lifting the upstream side in the transport direction of the cap relative to the floor surface, The exit-side fixed floor hangs down on the upstream side of the cap transfer direction with respect to the floor surface and has a vertical wall surface that is opposite to the vertical wall surface of the up-and-down moving floor. surface Ri Na is enabling repeatedly lifting operation to position the upper and lower with respect to the friction coefficient of the outlet-side fixed vertical wall of the floor is greater is set than the friction coefficient of the lifting floor vertically moving bed, wherein the vertical moving bed Is The vertical distance between the vertical wall surface of the outlet and the vertical wall surface of the fixed floor on the outlet side is set to be smaller than the shortest width in a plan view of the surface having the maximum area in the shape of the cap. In the upstream side, there is a guiding floor surface that forms a downward slope toward the downstream side in the cap conveyance direction .

  According to the present invention, the installation space for equipment necessary for flipping an article upside down is minimal, and various articles can be flipped up and down with a simple configuration without making the transport direction before and after the article is inverted reverse.

  The article reversing device 10 shown in FIG. 1 uses the inversion target article 1 as a cap, for example, and reverses the article 1 while transporting it, so that it can be dispensed to the next process.

  In the article reversing device 10, the vertically movable floor 30 and the outlet-side fixed floor 40 are arranged along the article conveyance direction. In this embodiment, a loading chute 20 is connected to the downstream side of an aligner (not shown) that aligns the vertical postures of the articles 1 at a constant level, and this charging chute 20 is arranged upstream of the vertical moving floor 30. Side guides 11 are erected on both sides of the input chute 20, the vertically movable floor 30, and the outlet side fixed floor 40. The charging chute 20 and the outlet side fixed floor 40 are fixedly sandwiched between the side guides 11 on both sides without any gap. The vertical moving floor 30 is moved up and down by the vertical lifting device 35 while being sandwiched between the side guides 11 on both sides without any gap. The side guide 11 prevents the article 1 on the throwing chute 20, the vertically movable floor 30, and the outlet-side fixed floor 40 from dropping in the lateral direction. The vertical elevating device 35 can employ a slider / link mechanism, a pneumatic cylinder, or an electric actuator that converts rotational motion into reciprocating linear motion. The vertical elevating device 35 is preferably an electric actuator in terms of easy setting of a stop position and speed control.

  The input chute 20 includes a plate-like chute and the like and has a downward slope toward the downstream side in the article conveying direction as shown in FIG. The downward inclination angle δ of the charging chute 20 will be described later.

  As shown in FIG. 2, the vertically movable floor 30 has a guiding floor surface 31, a vertical wall surface 32, and a lifting floor surface 33 in order from the upstream side to the downstream side in the article transport direction. The lift floor 33 has a downward slope toward the downstream side in the article conveyance direction. The vertical wall surface 32 stands vertically upward from the most upstream portion of the lifted floor surface 33 on the upstream side of the lifted floor surface 33 in the article conveying direction. The guiding floor surface 31 is disposed on the upstream side in the article conveyance direction with respect to the highest portion of the vertical wall surface 32, and forms a downward gradient toward the downstream side in the article conveyance direction. As shown in FIG. 3, the guiding floor surface 31 has a two-step gradient surface with a gentle slope 31A on the upstream side and a steep slope 31B on the downstream side, or a rounded convex curved surface at the uppermost stream portion. The articles 1 thrown in from the floor can be smoothly guided between the up-and-down moving floor 30 and the outlet-side fixed floor 40, and clogging of the articles 1 on the guided floor surface 31 can be avoided. The descending slope angle α of the guiding floor surface 31 and the descending slope angle β of the lifted floor surface 33 will be described later.

  As shown in FIG. 2, the outlet side fixed floor 40 has a vertical wall surface 41 and a floor surface 42 in order from the upstream side to the downstream side in the article conveyance direction. The vertical wall surface 41 hangs down in the vertical direction from the most upstream portion of the floor surface 42 on the upstream side in the article conveyance direction with respect to the floor surface 42, and faces the vertical wall surface 32 of the up and down moving floor 30 via a certain distance x. The floor surface 42 is inclined downward toward the downstream side in the article conveyance direction. However, the floor 42 may be a horizontal plane (FIG. 9). The intersection angle γ between the vertical wall surface 41 and the floor surface 42 will be described later.

  Here, the reversal target article 1 of the article reversing device 10 includes a cylindrical shape, an elliptical column shape, a rectangular column shape or the like having a bottom surface as shown in FIGS. 4 (A) to 4 (C). The solid substance shown in (D) may be used. Each article 1 has a top surface A and a bottom surface B. Then, the article reversing device 10 may flip the article 1 carried in upward on the top surface and pay it out downward, or flip the article 1 carried in on the top face downward and pay it out. Also good. The diameter of the top surface A or the bottom surface B of the article 1 is d, and the height of the article 1 is h.

  The article reversing device 10 repeats the lifting and lowering operation of positioning the lifting floor 33 of the vertically moving floor 30 at the upper and lower positions with respect to the floor 42 of the exit-side fixed floor 40 by the up-and-down lifting device 35, thereby moving the article 1 (top surface A). The bottom surface B) is inverted as follows (FIGS. 5 to 8). Here, the article 1 in which the aligner is aligned downward on the top surface is carried into the up and down moving floor 30 via the input chute 20 (FIG. 1A), and the article 1 inverted by the up and down moving floor 30 upward on the top surface. Is discharged from the outlet side fixed floor 40 to the next process (FIG. 1B).

  (1) When the up-and-down moving floor 30 is in the original position, the most upstream part of the guiding floor surface 31 of the up-and-down moving floor 30 is below the most downstream part of the charging chute 20. In this state, the top-down article (cap) 1 placed on the charging chute 20 upstream of the up-and-down moving floor 30 slides down toward the up-and-down moving floor 30 (FIG. 5A).

  (2) The article 1 passes through the guiding floor surface 31 of the vertically moving floor 30 and comes into contact with the three points of the lifting floor surface 33 and vertical wall surface 32 of the vertically moving floor 30 and the vertical wall surface 41 of the outlet side fixed floor 40. It stops (FIG. 5B).

  (3) When the up-and-down moving floor 30 starts to rise, the article 1 moves forward while sliding up the lifting floor 33 of the up-and-down moving floor 30 by the frictional force that the article 1 receives from the vertical wall surface 41 of the outlet side fixed floor 40. Rotate to get up (FIG. 5C). At this time, if the frictional force that the article 1 receives from the lifted floor surface 33 of the up-and-down moving floor 30 is small, the article 1 rotates so as to rise more easily forward.

  (4) When the vertically moving floor 30 further rises, the bottom surface side of the article 1 rises up to a position where it touches the vertical wall surface 41 of the outlet-side fixed floor 40, and the article 1 rises with the top surface and bottom surface vertical. (FIG. 5D).

  (5) The vertically movable floor 30 rises, and about 1/2 of the bottom surface of the article 1 passes through the vertical wall surface 41 of the outlet-side fixed floor 40 (FIG. 6A). The up-and-down moving floor 30 may continue to rise as it is. However, the temporary movement of the article 1 in the next process is more reliably performed by temporarily stopping and then rising again. This is because by stopping the up-and-down moving floor 30, the vertical wall surface 41 of the outlet-side fixed floor 40 and the article 1 are brought into contact with static friction having a large friction coefficient instead of dynamic friction.

  (6) When the vertically movable floor 30 rises and most of the bottom surface of the article 1 passes through the vertical wall surface 41 of the outlet-side fixed floor 40, the lifting floor 33 of the vertically movable floor 30 faces the downstream side exerted on the article 1. Due to the upward force, the article 1 falls forward with the apex on the upstream side of the floor surface 42 of the outlet side fixed floor 40 as the rotation center (FIG. 6B).

  (7) The article 1 is inverted on the floor surface 42 of the outlet-side fixed floor 40 (exit chute) so that the top surface is directed upward (FIG. 6C). The article 1 is transferred to the next step by sliding down a payout chute (not shown), the outlet side fixed floor 40 is moved, or an extruding device from the outside. As for the vertically movable floor 30, the most downstream portion of the lifted floor surface 33 rises to a higher level than the most upstream portion of the outlet side fixed floor 40.

  As described above (1) to (7), the article 1 can be turned upside down one after another by repeatedly raising and lowering the vertically moving floor 30. The raising / lowering cycle time of the up and down moving bed 30 is preferably 0.5 to 4.0 sec, and particularly preferably 1.0 to 2.5 sec. To shorten the lifting / lowering cycle time, an expensive vertical lifting / lowering device 35 is required, which is not economical. If the ascending / descending cycle time is too long, productivity decreases. The rising speed of the vertically moving bed 30 is preferably 50 to 300 mm / sec, particularly preferably 150 to 250 mm / sec.

  FIG. 7 corresponds to (1) to (4) among the reversing operations (1) to (7) shown in FIGS. 5 and 6 by the article reversing device 10, and in particular, (2), (3) (B) and (C) of FIG. 5 are different (FIGS. 7B and 7C). 9A and 9D are exactly the same as FIGS. 5A and 5D.

  That is, in contrast to the reversing operation (2) shown in FIG. 5 (B) by the article reversing device 10, in FIG. 7 (B), the article 1 passes the guiding floor surface 31 of the up and down moving floor 30, With momentum, the lifted floor surface 33 of the vertically moving floor 30 and the vertical wall surface 41 of the outlet side fixed floor 40 come into contact with each other and stop. The top surface of the article 1 is in a state of being tilted vertically or very slightly downward.

  Then, in contrast to the reversing operation (3) shown in FIG. 5C by the article reversing device 10, in FIG. 7C, when the vertically moving floor 30 starts to rise, the vertical wall surface of the outlet-side fixed floor 40 Due to the frictional force that the article 1 receives from 41, the top surface of the article 1 is not tilted downward, or until the bottom surface side of the article 1 contacts the vertical wall surface 41 of the exit-side fixed floor 40. Get up and rise. Since the frictional force that the article 1 receives from the lifting floor 33 of the up and down moving floor 30 is small, this movement is not hindered.

  In FIG. 8, the distance x between the vertical wall surface 32 of the vertically moving floor 30 and the vertical wall surface 41 of the outlet-side fixed floor 40 is conveyed onto the shortest width d of the article 1 (the floor surface 42 of the outlet-side fixed floor 40). (1) to (7) among the reversing operations (1) to (7) shown in FIG. 5 and FIG. A state (FIGS. 8B and 8C) in which the operation (FIG. 5B) is different is shown. 8A and 8D are different from FIG. 5A and FIG. 5C only in that the article 1 is smaller.

  That is, the reversing operation (2) shown in FIG. 5 (B) by the article reversing device 10 is the same as that shown in FIGS. 8 (A) to 8 (B), (C) because the article 1 is small (x> d). ) Through FIG. 8D, or from FIG. 8A immediately through FIG. 8C to FIG. 8D.

  First, in FIG. 8B, the article 1 passes through the guiding floor surface 31 of the up-and-down moving floor 30 and contacts two points of the lifting floor surface 33 of the up-and-down moving floor 30 and the vertical wall surface 41 of the outlet-side fixed floor 40. Then stop. When the up-and-down moving floor 30 starts to rise, the article 1 rotates so as to rise up forward by the frictional force that the article 1 receives from the vertical wall surface 41 of the outlet-side fixed floor 40, and shifts to the state of FIG. In rare cases, when the up-and-down moving floor 30 starts to rise, the state shown in FIG.

  In FIG. 8D, the article 1 passes through the guiding floor surface 31 of the up-and-down moving floor 30, and the entire top surface of the article 1 comes into surface contact with the lifting floor surface 33 of the up-and-down moving floor 30, and the exit side Stops in contact with the vertical wall surface 41 of the fixed floor 40. In rare cases, when the vertically moving floor 30 starts to rise, the state shown in FIG.

  Note that the distance x between the vertical wall surface 32 of the vertically movable floor 30 and the vertical wall surface 41 of the outlet side fixed floor 40 is the shortest width d of the article 1 (the article conveyed on the floor surface 42 of the outlet side fixed floor 40). Is set to be smaller than (the shortest width in top view of 1) (x <d) among the reversing operations (1) to (7) shown in FIGS. In 3), it is preferable that the article 1 is more easily tilted forward in the up-and-down moving floor 30 and easily reversed.

Hereinafter, a specific configuration of the article reversing device 10 will be described in detail.
(A) Angles of the floor surfaces of the input chute 20, the vertically movable floor 30, and the outlet fixed floor 40 (FIG. 2)
The downward inclination angle δ of the input chute 20 is adjusted to an angle at which the article 1 slides down due to its own weight. δ is preferably about 15 to 60 degrees, more preferably 20 to 40 degrees. By adjusting the slipperiness of the surface of the input chute 20, the quantity of articles 1 to be input to the up and down moving floor 30 can be adjusted appropriately. By making the input quantity appropriate, the subsequent article 1 is further fed back behind the article 1 that has entered between the vertical wall surface 32 of the up-and-down moving floor 30 and the vertical wall surface 41 of the outlet-side fixed floor 40, thereby turning upside down. Can prevent failure. Further, an article input device such as a belt conveyor type in place of the input chute 20 may be arranged horizontally or up. The belt conveyor type article input device is preferable because the number of articles 1 input to the up and down moving floor 30 can be easily controlled by the speed of the belt conveyor.

  The angle α of the descending slope of the guiding floor 31 of the vertically moving floor 30 is preferably increased to some extent so that clogging does not occur when the article 1 enters between the vertically moving floor 30 and the outlet-side fixed floor 40. However, it is better that α is not too large so that the height of the vertically movable floor 30 does not increase and the ascending / descending time becomes longer and the productivity is not lowered. α is preferably about 20 ° to 70 °, more preferably 40 ° to 60 °.

  The downward inclination angle β of the lifting floor 33 of the vertically moving floor 30 is preferably 70 degrees or less so that the article 1 can slide up the slope while the vertically moving floor 30 is rising. Moreover, it is preferably set to 30 degrees or more so that the vertically movable floor 30 rises and the article 1 is caused to fall into the front exit side fixed floor 40. β is preferably 30 ° or more and 70 ° or less, and more preferably 40 ° or more and 60 ° or less.

  The crossing angle γ of the floor surface 42 of the outlet side fixed floor 40 with respect to the vertical wall surface 41 is preferably 90 degrees or less. As shown in FIG. 9, γ is 90 degrees, that is, horizontal, and after receiving the article 1 on the outlet-side fixed floor 40, the article 1 is transferred by an extruding device from the outside, or the outlet-side fixed floor 40 is horizontal. The article 1 may be transferred to a desired position by moving or the like (FIG. 9B), or the outlet-side fixed floor 40 may be tilted to dispense the article 1. If γ is less than 90 degrees, the article 1 can slide down the floor surface 42 of the outlet side fixed floor 40 by its own weight and be transferred to the next process. Therefore, γ is preferably 30 to 90 degrees, more preferably 45 to 90 degrees.

(B) Relationship with the size of article 1 (Fig. 2)
The article 1 to be reversed by the article reversing device 10 preferably has a top or bottom diameter d larger than its height h (d> h). When the height h of the article 1 is large, depending on the shape of the article 1, the height direction of the article 1 may be perpendicular to the traveling direction in the apparatus, and it may not be possible to flip it upside down.

  The distance x between the vertical wall surface 32 of the up-and-down moving floor 30 and the vertical wall surface 41 of the outlet-side fixed floor 40 is set to be shorter than the shortest width d of the article 1 and the diameter d in the case of a circular article (x <d), The bottom surface side of the article 1 can be directed forward. Preferably, x is 30 to 70% of d, more preferably 40 to 60%.

  The distance x between the vertical wall surface 32 of the up-and-down moving floor 30 and the vertical wall surface 41 of the outlet-side fixed floor 40 is made larger than the height h of the article 1 (x> h). It enters between the vertical wall surface 32 and the vertical wall surface 41 of the outlet side fixed floor 40. In addition, by defining the upper limit of x, the inclination angle θ of the article 1 between the vertical wall surface 32 of the up-and-down moving floor 30 and the vertical wall surface 41 of the outlet-side fixed floor 40 is reduced, and the article is moved when the up-and-down moving floor 30 is raised. It is possible to prevent the top surface and the bottom surface of 1 from becoming difficult to become vertical. x is preferably 110 to 250% of h, more preferably 130 to 200%.

  The article 1 is adjusted by adjusting the angle β and the distance x of the descending slope of the lifting floor 33 of the up-and-down moving floor 30 so that the inclination angle θ of the article 1 is 60 degrees to 85 degrees, more preferably 70 degrees to 85 degrees. While the up-and-down moving floor 30 is rising, the lifting floor surface 33 is easily slid up and lifted with the top and bottom surfaces of the article 1 being vertical. And the up-and-down moving floor 30 rises further, and the article 1 can be made to fall into the front exit side fixed floor 40. In actual operation, the article 1 enters the space between the up and down movable floor 30 and the outlet fixed floor 40, and the top and bottom surfaces of the article 1 are vertical from the beginning, that is, θ is 90 degrees. Sometimes it is.

  When the size of the article 1 is changed, it can be dealt with by exchanging with a vertically movable floor 30 having a different distance x prepared separately.

(C) Friction coefficient between the lifted floor surface 33 of the vertically moving floor 30 and the vertical wall surface 41 of the outlet side fixed floor 40 (FIG. 2).
When the up-and-down moving floor 30 starts to rise, the article 1 rises forward while sliding up the lifting floor 33 of the up-and-down moving floor 30 by the frictional force that the article 1 receives from the vertical wall surface 41 of the outlet-side fixed floor 40. Rotate. In particular, when the frictional force that the article 1 receives from the lifted floor surface 33 of the up-and-down moving floor 30 is small, the article 1 rotates more easily to get up.

  For this reason, the friction coefficient μ2 of the vertical wall surface 41 of the outlet side fixed floor 40 is preferably increased. As an example, a method is used in which the material is a metal such as stainless steel, the surface is roughened, or the surface is grooved with a minute depth perpendicular to the traveling direction of the article 1. The friction coefficient μ2 of the vertical wall surface 41 of the outlet side fixed floor 40 is preferably 0.3 or more, and more preferably 0.5 or more.

  The friction coefficient μ1 of the raised floor surface 33 of the up and down moving floor 30 is preferably small. As an example, a fluororesin such as PTFE such as Teflon (registered trademark) or POM or the like is used as a slippery resin, a metal coated with Teflon (registered trademark), the surface is polished smoothly, the traveling direction of the article 1 on the surface A method of performing a groove processing with a minute depth parallel to the surface is used. The friction coefficient μ1 of the raised floor surface 33 of the vertically moving floor 30 is preferably 0.3 or less, more preferably 0.15 or less.

  The friction coefficient μ2 of the vertical wall surface 41 of the exit-side fixed floor 40 is made larger than the friction coefficient μ1 of the lifting floor surface 33 of the up-and-down moving floor 30 (μ2> μ1), so that the article 1 can be rotated to rise more reliably. can do.

(D) Floor width L of the vertically moving floor 30 (FIG. 1)
The floor width L (length orthogonal to the article transport direction) of the vertically moving floor 30 may be 1.5 times or more the maximum width of the article 1. By adjusting the floor width L, the necessary reversing ability can be obtained. As an example, when an up-and-down moving floor 30 having a floor width L that is five times the maximum width of the article 1 is operated at an elevating cycle time of 2.0 seconds, the up-and-down moving floor 30 has an average of about three articles per cycle. 1 is turned upside down, and the turning ability is about 90 pieces / min.

Therefore, according to the article reversing device 10, the following functions and effects can be obtained.
(a) When the article 1 whose top surface is directed downward from the loading chute 20 upstream of the up and down moving floor 30 is slid down to the up and down moving floor 30 side, the article 1 is lifted from the up and down moving floor 30 The surface 33 and the vertical wall surface 32 come into contact with three points of the vertical wall surface 41 of the outlet side fixed floor 40 and stop. When the up-and-down moving floor 30 starts to rise, the article 1 rises forward while sliding up the lifting floor 33 of the up-and-down moving floor 30 by the frictional force that the article 1 receives from the vertical wall surface 41 of the outlet-side fixed floor 40. Rotate. When the up-and-down moving floor 30 further rises, the bottom surface side of the article 1 rises to a position where it touches the vertical wall surface 41 of the outlet-side fixed floor 40, and the article 1 rises with the top surface and the bottom surface vertical. When the up and down moving floor 30 rises and most of the bottom surface of the article 1 passes through the vertical wall surface 41 of the outlet side fixed floor 40, the upward force from the lifting floor 33 of the up and down moving floor 30 toward the downstream side with respect to the article 1 The article 1 falls forward with the upstream apex of the floor surface 42 of the outlet side fixed floor 40 as the center of rotation. Thereby, the article 1 is inverted with the top surface facing upward on the floor surface 42 of the outlet side fixed floor 40.

  (b) By setting the friction coefficient μ2 of the vertical wall surface 41 of the fixed floor 40 on the outlet side to be larger than the friction coefficient μ1 of the lifting floor surface 33 of the up and down moving floor 30, the article 1 of (a) above is moved up and down. It can rotate so that it can get up to the front reliably on the lift floor 33 of 30. That is, when the up-and-down moving floor 30 starts to rise, the article 1 rises forward while sliding up the lifting floor 33 of the up-and-down moving floor 30 by the frictional force that the article 1 receives from the vertical wall surface 41 of the outlet side fixed floor 40. Rotate like so. In particular, when the frictional force that the article 1 receives from the lifted floor surface 33 of the up-and-down moving floor 30 is small, the article 1 rotates more easily so as to get up.

  (c) The distance x between the vertical wall surface 32 of the vertically movable floor 30 and the vertical wall surface 41 of the outlet-side fixed floor 40 is the shortest in the top view of the article 1 conveyed on the floor surface 42 of the outlet-side fixed floor 40. By setting it to be smaller than the width d, it is possible to rotate the article 1 of the above-mentioned (a) so as to be surely directed forward on the raised floor surface 33 of the vertically movable floor 30 and to be surely raised forward.

  (d) The vertically movable floor 30 has a guiding floor surface 31 that forms a downward slope toward the downstream side in the article conveyance direction on the upstream side in the article conveyance direction with respect to the vertical wall surface 32, The article 1 thrown from the loading chute 20 upstream of the above-described (a) up-and-down moving floor 30 can be smoothly supplied between the up-and-down moving floor 30 and the outlet-side fixed floor 40, and the clogging of the article 1 can be suppressed.

  (e) The exit-side fixed floor 40 is configured such that the crossing angle γ between the floor surface 42 and the vertical wall surface 41 is set to 90 degrees or less, whereby the floor of the exit-side fixed floor 40 in (a) described above. The article 1 inverted on the surface 42 can be dispensed smoothly.

  FIG. 10 shows an example in which the charging chute 20 of FIG. 1 is replaced with a belt conveyor type charging conveyor 100. The side guide 11 is connected to the outlet side fixed floor 40, and the input conveyor 100 is supported by a support means (not shown). The input conveyor 100 inputs, for example, the articles 1 aligned in the downward direction on the top surface by the aligner in the previous process to the up and down moving floor 30. The input conveyor 100 can be arranged so as to have a downward gradient in the article conveyance direction, or a horizontal or upward gradient, and the degree of freedom in the arrangement of the previous process is increased as compared with the case where an input chute is used. The input conveyor 100 may be operated continuously or intermittently, but an operation in which the amount of the articles 1 input to the up and down moving floor 30 is counted and controlled by a sensor or the like is particularly preferable.

  FIG. 11 shows an example in which the charging chute 20 of FIG. The lift feeder 200 alternately arranges a plurality of upstream fixed beds 201 and upstream moving beds 202 along the article conveyance direction, and each upstream fixed floor 201 and each upstream moving bed 202 are downstream in the article conveyance direction. Downhill floor surfaces 201A, 202A inclined so as to form a downward slope toward the side, and each upstream side movable floor 202 is disposed at the same time as the upper floor relative to the floor surface 201A of the upstream side fixed floor 201 adjacent to the floor surface 202A. Repeat the up-and-down movement positioned in the lower position. The side guide 11 is connected to the outlet-side fixed floor 40 and the upstream-side fixed floor 201, and the upstream-side movable floor 202 is moved up and down by a vertical lift device (not shown). Note that the up-and-down lifting device of the upstream moving floor 202 can be independent or combined with the up-and-down lifting device 35 of the up-and-down moving floor 30. By making it independent, reliable upside down and selection of an appropriate moving speed can be performed independently, and the apparatus can be easily adjusted.

  When the upstream moving floor 202 of the lift feeder 200 conveys the article 1 toward the fixed bed 201 on the downstream side by repeating the above-described lifting and lowering operation, the article 1 is on the side with the center of gravity, in other words, the top surface side of the cap faces downward. Are aligned and put on the side of the vertically moving floor 30.

  In the lift feeder 200, the vertical moving wall 30 and the outlet fixed floor 40 of the up and down moving floor 30 are synchronized by making the up and down timing of the upstream moving floor 202 the same as the up and down timing of the up and down moving floor 30. The failure of the upside-down inversion due to the subsequent article 1 being fed further behind the article 1 that has entered between the vertical wall surfaces 41 can be prevented. In this case, it is possible to reliably synchronize the upstream moving floor 202 and the vertical moving floor 30 by using the vertical lifting apparatus of the upstream moving floor 202 also as the vertical lifting apparatus 35 of the vertical moving floor 30, which is preferable. .

  The lift feeder 200 is arranged so that the individual floor surfaces 201A of the plurality of upstream fixed floors 201 are horizontally directed toward the downstream side in the transport direction, and the individual floors of the plurality of upstream moving floors 202 are arranged. The surfaces 202A are arranged so as to be horizontal toward the downstream side in the transport direction. However, in the lift feeder 200, the floor surfaces 201A of the plurality of upstream fixed floors 201 are arranged so as to form an upward slope toward the downstream side in the transport direction, and the plurality of upstream moving beds 202 are arranged. The individual floor surfaces 202A may be arranged so as to form an upward gradient toward the downstream side in the transport direction, or the individual floor surfaces 201A of the plurality of upstream fixed floors 201 may be disposed downstream of the transport direction. The floor surfaces 202A of the plurality of upstream moving floors 202 may be arranged so as to form a downward gradient toward the downstream side in the transport direction. The article feeder of the lift feeder 200 has a certain amount of articles 1 arranged on each floor surface 201A of the upstream fixed floor 201 and each floor surface 202A of the upstream moving floor 202. It is most preferable because the quantity of 1 can be easily controlled to a constant quantity.

  According to the present invention, the installation space for equipment necessary for flipping an article upside down is minimal, and various articles can be flipped up and down with a simple configuration without making the transport direction before and after the article is inverted reverse.
