Abstract

A container supply device 5 comprises a suction head 14, and this suction head 14 attracts and retrieves a container 2 from the lowest part of a magazine 4 and subsequently inverts the container 2 while descending, thereby supplying the container 2 to a pocket P at a supply position A. The movement of the suction head 14 when the container 2 is being inverted is controlled by a control device 10 via a rotation mechanism 23 and a lift mechanism 24. In other words, the control device 10 controls the inversion speed of the suction head 14 such that the container 2 is inverted at a constant speed. Because the container 2 can be prevented from separating from or shifting on the suction head 14 when the container is inverted, the container 2 can be reliably supplied into the pocket P.

Description

Container supply device

The present invention relates to a container supply device, and more particularly to a container supply device that feeds a container downward while feeding the container to a supply position on a lower side.

As is well known, there is a filling line for filling food such as pudding or jelly into a container. In such an existing filling line, the following method is sometimes employed. First, after the empty container is taken out of the box, the container is transferred to the lower side while the container is turned over, and then supplied to the lower side transport mechanism. In this case, after the container is supplied to the transport mechanism, the food such as the pudding is filled into the container transported by the transport mechanism, and then the sealing member is attached to the opening of the container by the sealing device.

However, in a filling line requiring a higher processing capability, if the filling device or the sealing device is operated at a high speed, it is also necessary to supply the container to the conveying mechanism at a high speed. In the container supply device, for example, as described in Patent Document 1 or Patent Document 2, after the empty container is taken out of the case, the container is inverted while being lowered, and then supplied to the lower supply position.

The apparatus described in Patent Document 1 has a horizontal rotating shaft 105 in which a plurality of holding members 106 are provided, and a cam plate 107 is attached to the horizontal rotating shaft 105. When the horizontal rotating shaft 105 and the holding member 106 are lowered, the rotating shaft 105 and the holding member 106 are rotated 180 degrees in the forward direction and the reverse direction, respectively, by engaging the cam plate 107 with the rotating cam 108. Thereby, the container held by the holding member 106 is lowered and turned over.

On the other hand, in the apparatus described in Patent Document 2, a plurality of suction nozzles 20 are provided in the cylindrical lifting/lowering portion 2, and the lifting/lowering portion 2 is rotated by a rotary cylinder or the like to suck The container held by the mouthpiece 20 is turned over.

However, the devices described in Patent Document 1 and Patent Document 2 have the following problems. That is, in the apparatus of Patent Document 1, if the holding member 106 is turned upside down at a high speed and lowered, the rotational speed of the container is increased, and the inertial force received by the container is increased. Therefore, in the apparatus of Patent Document 1, a pair of L-shaped pressing pieces 123 are rotatably attached to the right and left sides of the holding member 106, and the container is suctioned by the negative pressure of the holding member 106 while being pressed by the L-shaped pressing piece 123. The container is held at the upper portion of the holding member 106. Therefore, in Patent Document 1, the peripheral mechanism of the holding member 106 becomes complicated. Further, in the device of Patent Document 1, when the configuration in which the container is sucked and held by the negative pressure of the holding member 106 by omitting the pair of L-shaped pressing pieces 123 is employed, the container may be caused to be caused when the container is turned over. The holding member 106 is detached.

On the other hand, in the device of Patent Document 2, merely increasing the speed of rotation and lowering of the lift-and-reverse portion 2 causes an increase in the inertial force that the container receives, and there is a risk of occurrence of the same failure as in Patent Document 1.

In view of the above facts, the present invention provides a container supply device having: an adsorption head for detachably holding a container; a rotating mechanism for rotating the adsorption head; and a lifting mechanism for lifting and lowering the adsorption head and the rotating mechanism; In order to control the operation of the rotating mechanism and the lifting mechanism, the container supply device takes out the lowermost container in the tank by the suction head and transfers the container to the lower side, thereby inverting the container, thereby supplying the container to the supply position on the lower side. The control mechanism controls the operation of the rotating mechanism and the lifting mechanism, thereby The mechanism and the rotating mechanism cause the container to be inverted at a constant speed when the adsorption head of the holding container is lowered and turned over.

According to such a configuration, when the container is turned over by the adsorption head, the container is inverted at a constant speed, so that the container can be prevented from being detached or displaced from the adsorption head. Therefore, the container can be reliably supplied to the supply position by the high-speed inversion of the container by the adsorption head.

The invention will now be described with respect to the illustrated embodiment, in which reference numeral 1 denotes a filling and sealing system. The filling and sealing system 1 intermittently transports the container 2 by the transport mechanism 3 while filling the jelly into the container 2, and then seals the opening 2A of the container 2 with the sealing member S, and finally, cuts the seal adhered to the container 2. The extra part of the component S. The container 2 in the present embodiment is formed of a synthetic resin and has a cup shape in which the opening portion 2A of the upper portion is expanded.

The filling and sealing system 1 includes a transport mechanism 3 that holds the container 2 in a state in which the opening 2A faces upward and intermittently transports it to the downstream side, and a five-row box 4 that is disposed at the upstream end of the transport path of the transport mechanism 3, that is, the supply position. On the upper side of A, the container 2 is kept empty in a stacked state; the container supply device 5 simultaneously takes out a total of five containers 2 stacked in a row of five rows of boxes 4, and supplies them to the holder stopped at the supply position A. a groove P of 6; as a well-known filling device 7 of the prior art, The sealing device 8 and the trimming device 9 are sequentially disposed on the transport path of the transport mechanism 3 on the downstream side of the supply position A, and the control mechanism 10 controls the operation of the transport mechanism 3 and the respective devices 5, 7 to 9, and the like. .

The transport mechanism 3 has a pair of left and right endless chains (not shown) wound around the left and right sets of the sprocket wheels 11 and 11, and a plurality of plate-shaped retainers 6 are attached to the left and right endless chains. Each of the holders 6 is formed with five grooves P at equal intervals in a direction perpendicular to the conveying direction of the conveying mechanism 3. As shown in FIG. 2, the container 2 in a state in which the opening 2A is directed upward can be held in the five grooves P of the holder 6.

The sprocket 11 is interlocked with a motor (not shown) to perform intermittent rotation, and the control mechanism 10 controls a motor for intermittently rotating the sprocket 11. The control mechanism 10 intermittently rotates the sprocket 11 of the transport mechanism 3 in the direction of the arrow by a motor (not shown), whereby the retainers 6 (grooves P) are sequentially stopped at the supply position A for a predetermined period of time.

On the other hand, the five rows of tanks 4 of the container 2 which are kept in a stacked state are respectively disposed at positions above the respective grooves P at the same height corresponding to the respective grooves P of the holder 6 stopped at the supply position A. .

The container supply device 5 has five adsorption heads 14 arranged in a row in a row to correspond to the number of grooves P of the case 4 and the holder 6, and the adsorption head 14 is connected to a negative pressure source by a flexible tube (not shown). . The control unit 10 controls the supply and discharge operation of the negative pressure applied from the negative pressure source to the adsorption head 14, thereby adsorbing and holding the container 2 by the adsorption head 14 or releasing the holding state.

In the present embodiment, the lowermost container 2 of the five rows of boxes 4 are simultaneously sucked and held by the five adsorption heads 14, and then the container 2 is transferred to the lower side, and then supplied synchronously to the supply. The position A is in the five recesses P of the holder 6 in the stopped state. As will be described in detail later, since the five adsorption heads 14 of the take-out container 2 are reversed while being lowered, the container 2 in a state in which the opening portion 2A faces upward is synchronously supplied into the five grooves P.

A stopper mechanism 15 is provided at a lower portion of the five-row box 4, and the lowermost container 2 of the five rows of tanks 4 is supported by the stopper mechanism 15, and the lowermost container is smoothly taken out from the tank 4 by the adsorption head 14. 2. The container 2 in a state in which the opening 2A faces downward is accommodated in each of the cases 4 in a stacked state. The container 2 in the stacked state in the tank 4 is supported by the stopper mechanism 15. In addition, FIG. 1 and FIG. 2 are side views, so only one case 4 and one adsorption head 14 are shown.

As shown in Fig. 2, the stopper mechanism 15 has a pair of front and rear upper stoppers 16, 16' disposed opposite to each other, and a pair of front and rear lower stoppers 17, 17' disposed opposite each other; for the upper stopper 16, a group of cylinders 21, 21' that perform a forward and backward movement; and a group of cylinders 22, 22' for causing the lower stops 17, 17' to advance and retreat simultaneously. The operation of the cylinders 21, 21', 22, 22' is controlled by the control mechanism 10. When the lowermost container 2 of each tank 4 is sucked and taken out by the five adsorption heads 14, the control mechanism 10 is controlled by the cylinders 21, 21. ', 22, 22' causes each of the stoppers 16, 16', 17, 17' to perform the following advance and retreat operations.

That is, before the adsorption head 14 rises to the rising end near the position immediately below the tank 4, the cylinders 21, 21' do not operate, so the upper stoppers 16, 16' are located at the retracted position where the container 2 is not supported (the state of Fig. 2) ). On the other hand, the cylinders 22, 22' operate to advance the lower stoppers 17, 17' to the forward end, and the lowermost container 2 in each of the tanks 4 is supported by the forward lower stoppers 17, 17'.

In this state, the five adsorption heads 14 of the container supply device 5 are synchronously raised to the rising end in the vicinity of the position immediately below the respective boxes 4 at the corresponding positions. At this time, since the negative pressure is introduced to each of the adsorption heads 14, the lowermost container 2 in each of the tanks 4 is sucked and held by the corresponding adsorption heads 14. Next, the control unit 10 stops the operation of the cylinders 22, 22' and retreats the lower stoppers 17, 17', and simultaneously operates the cylinders 21, 21' to advance the upper stoppers 16, 16' to the forward end position. Thereby, the support state of the lower stoppers 17, 17' to the lowermost container 2 is released, and the penultimate container 2 in each of the tanks 4 is supported by the upper stoppers 16, 16'.

Thereafter, the adsorption heads 14 holding the lowermost container 2 are simultaneously lowered downward by a predetermined distance, and the lowermost container 2 is taken out from each of the tanks 4 by the adsorption head 14.

Thereafter, the cylinders 22, 22' are operated by the control mechanism 10 to advance the lower stops 17, 17' to the forward end, and then the operation of the cylinders 21, 21' is stopped by the control mechanism 10 to cause the upper stops 16, 16' back. Thus, the container 2, which was previously located second to last in the tank 4, is located at the lowermost portion, and the lowermost container 2 is supported by the lower stoppers 17, 17'.

As described above, the control mechanism 10 advances and retracts the upper stoppers 16, 16' and the lower stoppers 17, 17' of the stopper mechanism 15, thereby being synchronously taken out from the five rows of tanks 4 by the five adsorption heads 14, respectively. One of the lowermost containers 2.

On the other hand, a total of five adsorption heads 14 of the container 2 taken out from the five rows of boxes 4 are then lowered and inverted by the control mechanism 10 in accordance with the following movement trajectory, so that the container 2 held by the adsorption head 14 is also the same. The movement track drops and flips. That is, the control mechanism 10 causes a total of five adsorption heads 14 to be synchronously moved to realize the following three steps, that is, the step S1 of descending immediately below the container 2 after the container 2 is held at the rising end position; At the same time, the flipping step S2 of flipping 180°; and the step S3 of inserting the container 2 down to the falling end immediately after the inverting step S2 and feeding the container 2 to the groove P.

In this manner, the holding head 2 of the holding container 2 is moved by the three operation steps S1 to S3, and the container 2 held by the five adsorption heads 14 in the horizontal direction is supplied into the five grooves P of the supply position A. Further, when the container 2 is supplied into the recess P by the adsorption head 14, the control mechanism 10 stops supplying the negative pressure to each of the adsorption heads 14, thereby releasing the holding state of the adsorption head 14 to the container 2. Thereby, the container 2 whose opening part 2A faces upward is supplied into the groove P.

Thereafter, the adsorption head 14 is controlled by the control unit 10 to operate, rises and reverses from the position of the lower end, and returns to a position near the immediately below the tank 4, that is, the rising end, at which time, the control unit 10 is directed to the adsorption head. 14 Introduce negative pressure. Thus, the lowermost container 2 of the tank 4 at the corresponding position is adsorbed and held by the five adsorption heads 14. Thereafter, as described above, the container 2 is taken out from each of the tanks 4 by the adsorption head 14, and each time the holder 6 is stopped at the supply position A with the intermittent conveyance of the transport mechanism 3, the adsorption head 14 The container 2 is supplied into the recess P of the holder 6.

Then, with the intermittent conveyance of the conveyance mechanism 3, each container 2 held by the groove P of each holder 6 is conveyed to the downstream side, and the following processes are performed. In other words, when a total of five containers 2 in the horizontal direction in the holder 6 are carried into the filling position B with the opening 2A facing upward, a predetermined amount of jelly is filled into the five containers 2 in the horizontal direction by the filling device 7. Thereafter, after the holder 6 holding the filled container 2 is carried into the sealing position C, the band-shaped sealing member S is simultaneously attached to the opening portion 2A of the upper end of the five containers 2 in the horizontal direction by the sealing device 8. Thereby, the opening 2A of each container 2 is sealed by the sealing member S.

Thereafter, the container 2 to which the sealing member S is attached is carried into the trimming position D, and the excess portion of the sealing member S on each of the containers 2 is cut by the trimming device 9. That is, the sealing member S will be It is cut into the same shape as the outline of the opening 2A of the container 2.

In this way, for a total of five containers 2 held in a row and intermittently conveyed by the holder 6, the filling of the jelly, the attachment of the sealing member S, and the removal of the excess portion of the sealing member S are performed. Further, the five containers 2 in the horizontal row that have been processed and held by the holder 6 are removed from the holder 6 of the transport mechanism 3 by a discharge mechanism (not shown), and then transferred to the downstream side (not shown). The location of the gathering. In addition, the configuration of the filling device 7, the sealing device 8, and the trimming device 9 is a conventionally known configuration, and thus detailed description thereof will be omitted.

However, in the present embodiment, when a total of five adsorption heads 14 of the container supply device 5 are moved by the above-described respective steps S1 to S3, the adsorption head 14 and the adsorption head 14 are held in the inverting step S2. The container 2 is flipped at a constant speed to prevent the inverted container 2 from falling off or being displaced from the adsorption head 14.

Next, the configuration of the container supply device 5 will be described in detail. In FIGS. 3 to 5, the container supply device 5 has a column of five adsorption heads 14 for adsorbing and holding the container 2, a rotation mechanism 23 for synchronously rotating one column of the adsorption heads 14, and a suction head 14 and a rotation mechanism 23. The lifting and lowering mechanism 24 controls the operation of the rotating mechanism 23 and the lifting mechanism 24 by the control mechanism 10, and moves the adsorption head 14 in each of the above steps S1 to S3.

The container supply device 5 has a pair of left and right stays 25 and 25 disposed with the transport mechanism 3 interposed therebetween, and a pair of guide rails 26 and 26 are connected to the outer surface of the support post 25 in the vertical direction. The pair of left and right lifting members 31 are attached to the pair of right and left guide rails 26 and 26 by the sliding members 27 and 27, and the rotating shaft 32 is rotatably attached to the front end portions of the pair of lifting members 31 and 31. The rotating shaft 32 is horizontally supported on the transport mechanism 3 so as to be perpendicular to the transport direction of the transport mechanism 3. The five adsorption heads 14 are attached to the longitudinal direction of the rotating shaft 32 at equal intervals and the openings are oriented in the same direction. As described above, each of the adsorption heads 14 is connected to the negative pressure source by a flexible pipe (not shown), and the control mechanism 10 introduces a negative pressure or a negative pressure into the respective adsorption heads 14 as necessary. Thereby, the container 2 can be held by the adsorption head 14, or the holding state can be released.

One end of the rotating shaft 32 is connected to a servo motor 33 which is rotated by the control mechanism 10 in the forward and reverse directions by a required amount. In other words, the control unit 10 rotates the rotary shaft 32 in the forward and reverse directions by the servo motor 33, so that the opening of the five adsorption heads 14 in a row can be vertically upward and the vertical upward can be directed to the axis of the rotary shaft 32. The heart is rotated by 180° for the center of rotation, That is, the state in which the adsorption head 14 is inverted is moved. The rotating mechanism 23 of the present embodiment is constituted by a rotating shaft 32 and a servo motor 33.

Next, the elevating mechanism 24 for elevating and lowering the rotating mechanism 23 and the adsorption head 14 will be described. The rotating shaft 34 is rotatably supported by the upper end portions of the left and right pillars 25 and 25 in a horizontal state, and the rotating shaft 34 is interlocked with the servo motor 35 by a plurality of gears (not shown). The control unit 10 controls the operation of the servo motor 35, and if necessary, rotates the required amount in the forward and reverse directions by the control mechanism 10.

Both ends of the rotating shaft 34 project to the outside of the two pillars 25 and 25. The both ends of the rotating shaft 34 are connected to the left and right by a pair of right and left connecting mechanisms 36 and 36 formed by the rocking lever 29 and the connecting rod 30. Lifting members 24, 24. Therefore, when the servo motor 35 rotates in the forward and reverse directions by the control mechanism 10 to rotate the rotating shaft 34 in the forward and reverse directions, the two lifting members 31, 31, the rotating shaft 32, and the five adsorption heads 14 The left and right connecting mechanisms 36, 36 are moved up and down along the guide rails 26. Accordingly, the rotating shaft 32 and the five adsorption heads 14 disposed on the two lifting members 31, 31 are also raised and lowered. In the present embodiment, the elevating members 31, 31, the connecting mechanisms 36, 36, the rotating shaft 34, and the servo motor 35 constitute the elevating mechanism 24.

The rotation mechanism 23 and the elevation mechanism 24 of the container supply device 5 have the above-described configuration, and the control mechanism 10 controls the operation of the servo motor 33 of the rotation mechanism 23 and the servo motor 35 of the elevation mechanism 24 so that a total of five adsorption heads 14 are in a row. The operation steps S1 to S3 are performed between the rising end and the lower end, and more specifically, the operation of the servo motor 33 of the rotating mechanism 23 and the servo motor 35 of the lifting mechanism 24 are controlled so as to be in the inverting step S2. When moving, the center of the bottom surface of the container 2 that moves at the outermost side is moved at a constant speed, and the container 2 is taken out from the tank 4 and supplied to the groove P of the supply position A.

Next, the operation of the container supply device 5 according to an embodiment of the present invention will be described.

First, the control unit 10 controls the operation of the two servo motors 33 and 35, and the rotation mechanism 23 and the elevating mechanism 24 raise the adsorption head 14 in a state in which the opening faces upward to the ascending end near the lower side of each of the tanks 4 (refer to the figure). 2). At this time, since the negative pressure is introduced into each of the adsorption heads 14 by the control mechanism 10, the lowermost container 2 of the five rows of tanks 4 is suction-held by the respective adsorption heads 14.

Thereafter, as described above, the state in which the stopper mechanism 15 is supported by the container 2 in each of the cases 4 is released. Further, at this time, the holder 6 of the transport mechanism 3 is stopped at the supply position A on the lower side.

Next, the control mechanism 10 controls the operation of the servo motor 35, whereby the adsorption head 14 and the rotation mechanism 23 are lowered by a predetermined amount by the elevating mechanism 24. Thereby, the lowermost container 2 in each tank 4 is sucked and held by the adsorption head 14, and is taken out (takeout step S1).

Thereafter, the control mechanism 10 causes the servo motor 35 to continue to rotate, thereby lowering the adsorption head 14 by the elevating mechanism 24, and causing the servo motor 33 to rotate forward, so that the adsorption head 14 is reversed as shown in FIG. 2 by the rotation mechanism 23. Rotate in the hour hand direction (turn over step S2). In the present embodiment, in the middle of the inverting step S2, before the axis of the inverting adsorption head 14 is rotated to a substantially horizontal position, that is, in (a) to (b) of Fig. 6 indicating the operation of the inverting step S2, the rotation is made. The shaft 32 is lowered, but in the paths (b) to (d), the adsorption head 14 continues the inversion operation, and the control mechanism 10 raises the servo motor 35 by a predetermined amount in a direction opposite to the previous direction, thereby making the rotation shaft 32 rises. Thereafter, the control mechanism 10 rotates the servo motor 35 in the original rotational direction. Thereby, the inertial force by the lowering operation acting on the container 2 is canceled, and the inertial force acting on the container 2 can be reduced as compared with the case of the simultaneous downward tilting. Moreover, the downstroke can be shortened, and the container supply device 5 can be made compact.

Further, in Fig. 6, K1 indicates the moving point of the central portion of the bottom surface of the container 2, and K2 indicates the moving trajectory.

As shown in FIG. 2, by the inverting step S2, the adsorption head 14 and the container 2 held therein are formed on the imaginary vertical plane along the transport direction of the transport mechanism 3 by drawing an arc-shaped movement locus. Flip. The control unit 10 controls the rotation speeds of the two servo motors 33 and 35 so that the inversion speed of the center of the top surface of the container 2 when the container 2 is reversed so as to draw the movement trajectory becomes the constant speed.

In this way, in the inverting step S2, the center of the top surface of the container 2 sucked and held by the adsorption head 14 is reversed so that the container 2 can be prevented from falling off or being displaced from the adsorption head 14. Further, in the present embodiment, the two servo motors 33 and 35 are controlled to move at a constant speed in the center portion of the top surface of the container 2 located at the outermost side during the reversing operation. However, the present invention is not limited thereto, and the two servos may be used. The motors 33 and 35 are controlled such that the center of the entire container 2 or the center of the adsorption unit of the adsorption head 14 moves at a constant speed. By the inverting step S2, each container 2 held by the adsorption head 14 is inverted so that the opening portion 2A faces upward, and the container 2 is supported at the supply position A. Above the recess P in the stopped state.

Thereafter, the control mechanism 10 controls the operation of the servo motor 35, whereby the adsorption head 14 and the rotation mechanism 23 are lowered by the elevating mechanism 24 (into the step S3). Thereby, each container 2 held by the adsorption head 14 is inserted into the groove P of the corresponding position. When the container 2 is inserted into the recess P, the control mechanism 10 immediately stops the introduction of the negative pressure to each of the adsorption heads 14, thereby releasing the holding state of the container 2 by the adsorption head 14, so that the respective containers 2 are supplied with the opening 2A facing upward. Inside the groove P.

In this manner, the adsorption head 14 that is controlled by the control unit 10 passes through the three operation steps S1 to S3 to supply the container 2 into the five grooves P in the stopped state at the supply position A.

Thereafter, the control unit 10 controls the operation of the servo motor 35 to raise the adsorption head 14 in which the holding state of the container 2 is released at the lower end, and the adsorption head is controlled by the control mechanism 10 to control the operation of the servo motor 33. The direction 14 is reversed in the opposite direction to the inversion step S2, thereby returning to the rising end of the position immediately below the respective boxes 4.

Further, in the above embodiment, a plurality of adsorption heads 14 are mounted on the rotary shaft 32 in the same direction, but as shown in Fig. 7, the position is shifted by 180 in the circumferential direction of the rotary shaft 32. Two sets of adsorption heads 14 are mounted on the rotating shaft 32. In the case where two sets of the adsorption heads 14 are installed, after a group of adsorption heads 14 feeds the container 2 into the grooves P, the rotation shaft 32 is directly raised, so that the other group of adsorption heads 14 can be positioned at the rising end, thus The embodiment can operate at a higher speed than the embodiment.

Thereafter, each time the holders 6 of the transport mechanism 3 are intermittently moved and stopped at the supply position A, as described above, the container 2 is taken out from the tank 4 by the adsorption head 14 of the container supply device 5, and the container 2 is turned over. Then, it is supplied into the groove P of the holder 6 of the supply position A. Then, as described above, the container 2 that is transported intermittently to the downstream side by the holder 6 of the transport mechanism 3 performs processing such as filling of the jelly, attachment of the sealing member S, and removal of the excess portion.

Further, in the above embodiment, the container 2 is inserted into the groove P of the holder 6 in the temporarily stopped state at the supply position A by the adsorption head 14, but it is also possible to move the supply position A in the conveyance direction. The holder 6 causes the adsorption head 14 to follow the movement in the conveying direction to move the container 2 is inserted into the groove P. By adopting such a configuration, the container 2 can be supplied at a higher speed.

Further, in the above-described embodiment, the container 2 in the state in which the bottom surface is kept upward in the tank 4 is taken out and inverted, and then supplied to the groove P of the holder 6, but it cannot be considered as a place for defining the orientation or supply of the container 2. . The container 2 in a state in which the bottom surface is kept downward in the tank 4 can be taken out, and the container 2 can be supplied to a place other than the holder 6.
