  As shown in FIG. 1, the cleaning line system 1 according to the present invention and the feeding device for the container dolly cart used therein are appropriately provided with the feeding device 4 at the container loading portion 4 and the unloading portion 5 in the cleaning line. Thus, the automatic movement of the dolly cart 9 is achieved, and the dolly cart 9 stacked using the car cart 10 is transferred from the carry-in section 4 to the carry-out section 5, thereby saving human labor. is there.

  The feeding device (comprising the feeding cylinder 2 and the orthogonal feeding cylinder 3) according to the present invention will be described. First, as shown in FIG. 2 and FIG. 3A, the feed cylinder 2 constituting the feed device is parallel to the dolly cart 9 along the feed direction a of the transport conveyor 1b that transports the containers 1a of the cleaning line system 1. Is for moving.

  As shown in FIGS. 2 and 6, the dolly cart 9 is for loading a container (container 1 a) used for transporting food or the like, and is a frame that is a rectangular metal casing. Body 9a, L-shaped hanging members 9b and 9d, which are suspended from a part of the body and suspended vertically, and can be rotated around a vertical support shaft provided at the corner of the body. And a rolling wheel (for example, a caster) 9c that is movable in all horizontal directions.

  The pair of the latching members 9b and 9d are provided so that the latching position when the dolly cart 9 is moved is symmetrical, and the front and rear directions of the dolly cart 9 are limited. This is to prevent it from being done. Moreover, although the rectangular shape from which the vertical and horizontal length of a housing | casing differs is not limited to this example, a square housing | casing may be sufficient depending on the shape of the container 1a.

  There is a feed cylinder 2 installed on the floor 8 on which the washing line system 1 is installed with a gap from the bottom of the dolly cart 9. A plurality of the feed cylinders 2 are installed on the floor surface 8 in two locations in this embodiment, and are arranged in parallel along the feed direction a of the conveyor 1b as shown in FIG. The driving means for the feed cylinder 2 is, for example, an electric type or an air type and is not particularly limited.

  As shown in FIG. 3A, the first rod 2c of the first feed cylinder 2a and the second rod 2d of the second feed cylinder 2b, which are rods in the plurality of feed cylinders 2, are fed by the dolly cart 9. Strokes are set so as to complement the movement distance (A → B stroke S1) in the direction a.

  In addition, a rod-like or plate-like pushing portion 2e protrudes upward in the vertical direction at the distal ends of the first rod 2c and the second rod 2d. As shown in FIGS. 5A (A) and 5 (B), the pushing portion 2e is set to a height that abuts against a latching member 9b suspended from the lower surface of the dolly cart 9 at its tip. . Further, in the drawing, a rotation stop member 2g is provided so that the push portion 2e does not rotate clockwise. Further, the pushing portion 2e is rotatable counterclockwise in the drawing. For example, it can rotate within a range of about 90 degrees. A return elastic member (not shown) such as a torsion spring is wound around a support shaft that rotatably supports the pressing portion 2e.

  By providing the pushing portion 2e having such a configuration, as shown in FIG. 5A, the dolly cart 9 moves along the feeding direction a, and the leading ends of the first rod 2c and the second rod 2d. When the latching member 9b of the dolly cart 9 collides with the pushing portion 2e while passing through the pushing portion 2e, the pushing portion 2e rotates counterclockwise and inclines and retracts. And if the said latching member 9b advances in the feed direction a and passes, the engagement action which pushes in the feed direction a will be cancelled | released, and the original state which protruded upwards by the urging | biasing force of the said return elastic member Then, the pushing portion 2e is returned.

  The pushing portion 2e of the feed cylinder 2 not only contacts a part of the dolly cart 9 and engages so as to be movable in the feed direction a, but is also rotatable within a certain range around a support shaft. When the carriage 9 passes, it is retracted in an inclined state. Further, when a part of the dolly carriage 9 passes, it is reversely rotated from the inclined state and returned to the original protruding state. It is.

  As shown in FIG. 5A, the dolly cart 9 that has moved along the feed direction a from the right hand side by the cooperation of the first feed cylinder 2a and the second feed cylinder 2b of the feed cylinder 2 is denoted by reference symbol A. From the position (the position reference of the dolly cart 9 is the center position in the feed direction a), the feed is sent to the position indicated by the symbol B. The drive switching between the first feed cylinder 2a and the second feed cylinder 2b is performed by a control device that detects the position of the slide table 2f with a sensor and receives the movement completion signal. .

  Next, the orthogonal feed cylinder 3 constituting the feed device that moves the dolly cart 9 in the orthogonal direction b orthogonal to the feed direction a will be described. As shown in FIG. 3B, the orthogonal feed cylinder 3 is for moving the dolly cart 9 in the orthogonal direction b orthogonal to the feed direction a of the conveyor 1b that conveys the containers 1a of the cleaning line system 1. is there.

  There is a first orthogonal feed cylinder 3a and a second orthogonal feed cylinder 3b installed along the orthogonal direction b on the floor surface 8 where the cleaning line system 1 is installed with a gap from the bottom surface of the dolly cart 9. As shown in the figure, a series (tandem) arrangement is adopted. As an example, the cylinder shafts are arranged in series, but the arrangement is not limited to this, and the cylinder shafts may be offset by being shifted toward the feed direction a.

  As shown in FIG. 5B, each of the first dolly carts 9 is moved by the stroke S2 in the orthogonal direction b that is driven by the first and second orthogonal feed cylinders 3a and 3b and orthogonal to the feed direction a. There are an orthogonal rod 3c and a second orthogonal rod 3d.

  The stroke (cd) of the first orthogonal rod 3c is about 300 mm, for example, and the stroke (de) of the second orthogonal rod 3d is about 460 mm, for example. Further, there is a pushing portion 3e that protrudes upward at the tip of each of the rods 3c and 3d and that is movably engaged by abutting against a part 9e of the frame body 9a of the dolly cart 9. .

  As shown in FIG. 5B and the upper drawing, the pushing portion 3e protruding from the first orthogonal rod 3c is fixed so as not to rotate. On the other hand, the pushing portion 3e is fixed to the second orthogonal rod 3d. The projecting push portion 3e has the same structure as the push portion 2e in the feed cylinder 2 described above, and does not rotate in the clockwise direction, but rotates in the range of about 90 degrees in the counterclockwise direction. This is because the dolly cart 9 does not pass over the first orthogonal feed cylinder 3a. On the other hand, the dolly cart 9 passes over the second orthogonal feed cylinder 3b.

  Thus, as shown in FIGS. 3B and 5B, the first orthogonal feed cylinder 3a and the second orthogonal feed cylinder 3b allow the dolly cart 9 to move in the orthogonal direction b while complementing the stroke cd + stroke de. Is moved only by the stroke S2. The drive switching between the first orthogonal feed cylinder 3a and the second orthogonal feed cylinder 3b is performed by a control device that detects the position of the slide table 3f with a sensor and receives the movement completion signal. It is.

  As described above, the feed cylinder 2 for sending the dolly cart 9 in the direction along the feed direction a of the conveyor 1b and the orthogonal feed cylinder 3 for sending the dolly cart 9 in the orthogonal direction b orthogonal to the feed direction a are formed. A method of cleaning the container 1a by applying this to the cleaning line system 1 will be described.

  In the washing line system 1, as shown in FIG. 1, the carrying-in section 4 for transferring the containers 1a to the conveyor 1b includes a feed cylinder 2 and an orthogonal feed cylinder 3 which are feed devices for a container dolly cart. To do. Further, the dolly cart supply device 12 in the carry-out section 5 for transferring the containers 1a from the conveyor 1b to the dolly cart 9 is provided with an orthogonal feed cylinder 3.

In the carry-in section 4, as shown in FIGS. 1 to 3 -A, an empty car 10 (see FIG. 6) is set in advance on the dolly cart loading device 11. The car 10 can travel on the floor surface 8 by the rolling cart 10c together with the rolling cart 9c of the dolly cart 9 stacked inside with the casing 10a as a guide, and can stably transport the stacked dolly cart 9 Structure.
From the container place 6 before cleaning, the dolly cart 9 on which the containers 1a are stacked and loaded is manually transported and set at a predetermined position A (see FIG. 2) of the container transfer machine 1h.

  When the start button of the container transfer machine 1h is pushed, the loaded container 1a is lifted up to the height position of the transfer conveyor 1b by the elevating unit 1d, and further on the transfer conveyor 1b downstream by the transfer conveyor 1c. It is transferred to.

  Next, the elevating unit 1d is lowered, and the containers 1a are placed on the conveyor 1b. The transfer conveyor 1c is returned to the original upstream position. The container 1a before cleaning is conveyed to the front of the cleaning line. The operator goes to the pre-cleaning container place 6 to take the next dolly cart 9.

  As shown in FIG. 2, FIG. 3-A and FIG. 5-A, the dolly cart 9 emptied after the container 1a is transferred onto the transport conveyor 1b is installed under the transport conveyor 1b. It is moved along the feed direction a from the A position to the B position by the feed cylinder 2 which is the feed device.

  That is, as shown in FIG. 5-A, the upper diagram, when the dolly cart 9 is manually carried in from the right hand side and the hooking member 9b collides with and presses the pushing portion 2e at the tip of the first rod 2c, The pushing portion 2e rotates counterclockwise and tilts to escape. When the hooking member 9b further enters and passes, the pushing portion 2e returns to the original protruding state. The dolly cart 9 is manually stopped at the position indicated by the symbol A.

  Here, when the first feed cylinder 2a is driven by a command from the control device, the slide table 2f and the first rod 2c advance in the feed direction a. At the same time, the pushing portion 2e moves, abuts against and presses against the latching member 9b of the dolly cart 9, and moves the dolly cart 9 from the position indicated by the symbol a (position A) to the intermediate position indicated by the symbol b. The slide table 2f and the first rod 2c move backward to return to their original positions.

  During the movement to the intermediate position, the dolly cart 9 rotates the pushing portion 2e of the second rod 2d counterclockwise with the latching member 9b, and after passing, the pushing portion 2e is urged by the urging force of the elastic member. It is returned to the original protruding position. Thereafter, the second feed cylinder 2b is driven by the control device that has received the movement completion signal by the sensor.

  As shown in FIG. 5-A, the lower diagram, when the second feed cylinder 2b is driven, the slide table 2f and the second rod 2d advance along the feed direction a. As a result, the pushing portion 2e contacts and presses against the latching member 9b, and the dolly cart 9 is moved from the position indicated by the symbol b to the position indicated by the symbol c (position B). The slide table 2f and the second rod 2d move backward and return to their original positions.

  In this way, as shown in FIG. 3A, the dolly cart 9 has the stroke (ab + bc) from the A position to the B position complemented by the first feed cylinder 2a and the second feed cylinder 2b. , The stroke is moved by S1.

  Further, as shown in FIGS. 3B and 5B, the orthogonal feeding cylinder 3 which is a feeding device performs a transfer action of complementing the strokes of the first orthogonal feeding cylinder 3a and the second orthogonal feeding cylinder 3b described above. Thus, the dolly cart 9 is transferred from the C position to the D position along the orthogonal direction b.

  That is, as shown in FIG. 5-B, the upper diagram, when the first orthogonal feed cylinder 3a is driven by the control device, the slider table 3f and the first orthogonal rod 3c move along the orthogonal direction b. The pushing portion 3e is pushed in contact with a part 9e of the frame body 9a of the dolly cart 9. In the dolly cart 9, the rolling wheel 9c appropriately rotates around the support shaft, and moves along the orthogonal direction b. The dolly carriage 9 is moved from the C position by the stroke cd by the first orthogonal feed cylinder 3.

  Next, as shown in FIG. 5-B, the lower diagram, when the dolly cart 9 passes over the second orthogonal feed cylinder 3b, the pushing portion 3e protruding from the second orthogonal rod 3d is temporarily It rotates counterclockwise and returns to its original position by the biasing force of the elastic member after passing through the dolly cart 9. Thereafter, the second orthogonal feed cylinder 3 is driven by a command from the control device.

  When the second orthogonal feed cylinder 3b is driven, the slide table 3f and the second orthogonal rod 3d move along the orthogonal direction b orthogonal to the feed direction. The pushing portion 3e comes into contact with the inside of a part 9e of the frame body 9a in the dolly cart 9. The pushing portion 3e does not rotate in the clockwise direction because of the rotation-preventing member 3g, and pushes and sends out the dolly cart 9, moves it by the stroke de, and moves the center position of the dolly cart 9 to the D position. In this way, as shown in FIG. 6, the dolly cart 9 is transferred to the car 10 set between the dolly cart stacking devices 11.

  As shown in FIGS. 4A and 4B, the dolly cart 9 transferred to the car 10 has claws 11a protruding from the pair of dolly cart stacking devices 11 and 11, respectively. It enters the interior from the lifting space 10b formed in the body 10a. By engaging the claw 11a with the lower surface of the frame body 9a of the dolly cart 9, the dolly cart 9 is supported by the claw 11a protruding from both sides.

  The lift devices 11 b of both the dolly cart stacking devices 11, 11 lift the dolly cart 9. This lifted state is maintained, and then it is waited for the dolly cart 9 to be transferred. If the next dolly cart 9 is transferred to the lowermost part of the car 10, the lift device 11 b is lowered and lifted by a command from the control device that is detected by a sensor or the like and that signal is input. One or a plurality of dolly carts 9 are stacked on the lowermost dolly cart 9.

  The claw 11 a of the dolly cart stacking device 11 moves to the outside of the car 10 and is immersed in the loading device 11. Further, the lift device 11b is lowered to the lowest position. The claw 11a is projected again, and the lowermost position of the dolly cart 9 is lifted and waited. In this manner, the stacking operation is repeated, and the empty dolly cart 9 is stacked on the car 10 in, for example, about 15 levels.

  As shown in FIG. 1, the car 10 in which the dolly carts 9 are stacked is manually conveyed to the vicinity of the dolly cart supply device 12 in the carry-out unit 5 of the cleaning line.

  As shown in FIG. 1, the stacked containers 1 a that are transported to the transport conveyor 1 b of the cleaning line are supplied by being separated by a corrugating apparatus, washed by a washing machine 1 e through an inversion machine, and then dried by a drying machine 1 f. Thereafter, the containers 1 a are stacked by the reversing machine and the stacker 1 g and reach the unloading unit 5.

  In the dolly cart supply device 12, a car 10 in which the dolly carts 9 are stacked is set. The dolly cart 9 is automatically stepped from the dolly cart supply device 12. The single dolly cart 9 separated in stages is transferred to the transfer section of the container transfer machine (similar to the transfer machine shown in FIG. 2) by the orthogonal feed cylinder 3 constituting the feed device provided under the conveyor. Set.

  That is, as shown in FIG. 5B, the first orthogonal feed cylinder 3a and the second orthogonal feed in the orthogonal feed cylinder 3 according to the command of the control device to which the completion signal from the set completion detection sensor is inputted. The slide table 3f with the cylinder 3b is driven along the orthogonal direction b. 3D. The container transfer machine is transferred from the dolly carriage supply device 12 side by the transfer action of the orthogonal feed cylinders 3 that act oppositely to the case shown in FIG. It is transferred to the part side.

  The washed containers 1a stacked in a stack are automatically transferred to the dolly cart 9 of the transfer section. The operator takes out the dolly cart 9 loaded with the containers 1a from the transfer machine and transports it to the container-cleaned storage site.

  As described above, the container 1a is cleaned by the cleaning line system 1 in which the feed cylinder 2 and the orthogonal feed cylinder 3 are provided in the carry-in unit 4 and the orthogonal feed cylinder 3 is provided in the transport unit 5.
