Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention relates to a conveying device for clothing and other various articles.

(2) Prior art For example, in a clothing wrinkle removal device that uses hot air and steam to remove wrinkles from clothing, minimizing the entrance and exit of the clothing can reduce the dissipation of hot air and steam outside the device. Energy consumption can be reduced.

Furthermore, for processing by hot air injection or steam injection within the apparatus, it is better to hang the clothes horizontally, with the front and back sides perpendicular to the direction of travel. That is,
By horizontally hanging clothes in this way, the pitch of the traveling member provided with hangers for hanging clothes can be minimized. Furthermore, in order to increase the residence time of clothes in a short apparatus and improve processing efficiency, it is necessary to hang the clothes horizontally as described above and to increase the speed of the conveyance chain in the apparatus.

Previously, in order to change the conveyance speed as described above, a fast-speed chain and a slow-speed chain were set up separately, and the heights of both chains were changed so that the clothes could be transferred from one chain to the other. .

(3) Problems to be Solved by the Invention When chains with different speeds are used as described above, there are problems such as falling accidents at the transition area between the conveyor chains with different speeds.
Further, similar problems occur when flat articles such as thin plate moldings, which have a large width relative to their thickness, are dried on a coating line or when the articles are carried into and out of a printing apparatus. In addition, there are many cases where it is necessary to change the conveyance direction or the conveyance speed without changing the posture of the article to be conveyed.

(4) Means for Solving the Problems In order to solve the above problems, the present invention provides a traveling member that conveys an article while moving along a guide groove provided in an endless guide rail, and a guide for the article. In the conveying device, the endless chain is arranged along the rail and driven by an appropriate driving means, and the endless chain is provided with a pushing piece for pushing the traveling member. A rectangular circulation path is formed by the right-angled bends, and sprockets with which the endless chain engages are arranged at each right-angle turn, and the running member slides in contact with the inner side wall of the guide rail from the side surface. The planar surface is square, and the travel locus of the push piece at the bending corner of the guide rail is located at the right-angled bend so that the contact point of the push piece and the running member draws an arc concentric with the center of the horizontal plane of the running member. When the center line of the horizontal plane of the traveling member and the center line of each sprocket are aligned, and at a predetermined position of the guide rail, the guide groove and the inner side wall are displaced in a direction away from the endless chain, and this At this position, the running members separate from the pushing pieces of the endless chain, and each running member is pushed only by the succeeding running member, so that the running speed of the running member at this part is equal to the running speed of the endless chain. A low-speed chain configured to run at a lower speed than the endless chain, and a low-speed chain consisting of an endless chain having a lower running speed than the endless chain is arranged in parallel inside the endless chain, and is provided on the guide rail at a predetermined portion. The guide groove and the inner side wall of the traveling member are displaced in the direction of the low-speed chain, and the traveling member is pushed in this portion by the push piece of the low-speed chain.

(5) Effect This invention has the above-mentioned configuration, in which an endless chain is run along an endless guide rail, and a traveling member that moves along a guide groove provided in the guide rail is pushed by a push piece provided in the endless chain. let it run,
Desired items are conveyed by this member. At this time, at the right angle bend of the guide rail, the endless chain to which the push piece is attached moves along the circumference of the sprocket that is concentric with the center of the horizontal plane of the running member located at the bend. Therefore, the contact point between the end of the pushing piece and the running member only rotates along the circumference concentric with the center of the sprocket and does not push the running member, so the running member stops during this period. When the push piece travels around the corner and enters the straight section, the push piece pushes the running member again and starts running, allowing clothing to be attached and removed while the vehicle is stopped.

In addition, in the case where the guide groove provided in the guide rail is displaced at a predetermined part, the running member is not pushed by the pushing piece of the chain in this part, but is pushed by the following running member and moves intermittently, so the running member moves intermittently. The speed will be slower. Furthermore, a low-speed chain that runs at a slower speed than the endless chain is installed in parallel with the endless chain, and the position of the guide groove of the running member provided on the guide rail is laterally displaced in the required part, so that the low-speed In the case where the running member is configured to be pushed by the pushing piece of the chain, when the running member enters the displacement part of the guide rail, it is pushed by the pushing piece of the low-speed chain and its traveling speed becomes slow.

The guide rail 5 has a rectangular cross section as shown in FIGS. 6 and 7, and in the embodiment shown in FIGS. 3 to 7, one endless chain 6 is disposed inside thereof over the entire length.

8 in FIG. 1 is a drive shaft that connects the guide rail 5 through a reducer (not shown) attached to the front upper part of the device 1.
Drives the chain drive sprocket 9 inside. As shown in Figures 2 and 3, this sprocket 9 is located at a right-angled bend e in the transition from the return part a to the inlet part b, and inside the other right-angled bends f, g, and h, there are rotating parts. Freely adjustable guide sprocket 10,1
1 and 12 are provided, and each guide sprocket 1
By engaging the endless chain 6 with 0, 11, 12 and the drive sprocket 9, the chain 6 is configured to travel within the guide rail 5 while maintaining a constant position. The upper part of the guide rail 5 is kept on the outside.

13 in FIGS. 2 to 7 is a guide groove provided at the bottom of the guide rail 5, and 14 is a slider that is slidably fitted into the guide groove 13 and whose upper end runs on the bottom of the guide rail 5. The running member 15 is fixed.

The running member 15 has a square planar shape, and its side surface is brought into contact with the side wall of the guide rail 5 so that it cannot rotate.
A hook plate 17 is swingably attached to the endless chain 6, and a plurality of push pieces 19 are provided at the bottom of the endless chain 6.
are fixed at regular intervals, but this push piece 19
As shown in the figure, its lower end is bent into an L-shape onto the running member 15, and a shaft 18 that is pushed by the lower end of the pusher piece 19 is provided at the upper center of the running member 15.

The shaft 18 on the running member 15 and the center of the slider 14 are concentric, and the center of the shaft 18 on the running member 15 at each bending angle e, f, g, h of the guide groove and each sprocket 9, 10, 11 , 12 so that their centers coincide. Note that in FIG. 3, the centers of the shaft 18 and the sprockets 9, 10 do not coincide for reasons of notation, but in reality, the centers of the shafts of the sprockets 9, 10 are stopped at the bending angle of the guide groove 13. It coincides with the center of the axis 18 of the member 15.

In addition, the width of the guide rail 5 of the processing section c between the bending angles f and g in the device 1 is made larger than other parts, and the guide groove 13 is moved slightly forward, that is, returns from a portion slightly inward from the bending angles f and g. The shaft 18 of the traveling member 15 that has entered this portion is moved away from the push piece 19 by being deviated toward the portion a.

In addition, the intervals between the push pieces 19 provided on the chain 6 are set large to be suitable for vertically feeding the clothes, and the running member 1
5 is the size of the hook plate 17 of the front and rear members 15 when the front and rear running members 15 contact each other.
The gap is short enough to allow air to circulate between the hanging clothes, and is shorter than the gap between the push pieces 19.

In the above embodiment, in the return section a, the traveling member 15 travels while being pushed by the pusher piece 19 of the chain 6, and the hook plate 17 is oriented horizontally with respect to the traveling direction, but there is no clothing ever. .

In this way, the traveling member 15 is not covered with clothing.
is pushed by the push piece 19 of the chain 6 and moves at high speed in the return section a, and when it comes to the bending angle e of the guide groove 13, the chain 6 rotates along the circumference of the sprocket 9, and the push piece attached to it moves 19 rotates around the shaft 18 of the member 15 within the bending angle e, so the member 15 is at rest during this period. Therefore, during this time, the hanger on which the clothes are hung is placed on the hook plate 17.
to engage.

Member 1 temporarily stopped at the bending angle e above.
5, the pusher piece 19 turns 90° and enters the straight part of the chain 6 at the inlet b, and at the same time the pusher piece 19 pushes the shaft 18 again and heads toward the inlet 2.

Since the traveling member 15 remains stationary and does not change its direction even when turning at the bending angle e as described above, the clothes should be hung on the hook plate 17 so that the front and back sides of the clothes are parallel to the chain 6 at the entrance part b while the traveling member 15 is stationary. According to
At the entrance part b, the clothes are fed vertically and enter the wrinkle removing device 1 through the narrow entrance 2.

The traveling member 15 that has entered the device 1 and reached the first bend f does not change its direction as in the case of the bend e, but only the direction of travel changes and enters the processing section c, so that the clothing 20 is moved as shown in FIG. It will be horizontally placed. The member 15 that has entered the processing section c in this way is inserted into the guide groove 13.
Move forward along. Therefore, the pusher piece 19 is
The member 15 moves further away and travels together with the chain 6, and then the member 15 stops.

Due to the above action, it enters the processing section c one after another,
The member 15 separated from the push piece 19 comes into contact with each other back and forth as shown in FIG. 3, and moves intermittently as it is pushed by the subsequent member 15 moving from the bending angle f.

Therefore, during this time, the member 15 moves much later than the movement of the chain 6, so the garment 20 moves in a short pitch, and wrinkles can be removed during this time.

The member 15, on which the wrinkles have been removed in this way, hangs the clothes, approaches the chain 6 again before turning the corner g, and its shaft 18 is pushed by the push piece 19, enters the corner g, and heads toward the entrance 3. Since the running member 15 does not change direction but only the running direction, the clothing 20 is again fed vertically and exits from the narrow exit 3, passes through the exit d, and when the member 15 stops once at the bending angle h, the wrinkles are removed. Remove the hanger with the removed clothes from the hook plate 17. Therefore, the empty hook plate 17 moves to the return section a.

8 and 9 show another embodiment, in which the configuration is the same as that of the first embodiment except that another endless low-speed chain 21 is disposed inside and below the endless chain 6. Therefore, the same reference numerals are given and the explanation will be omitted.

The chain 21 has a driving sprocket 22 provided on the inside of the bending angle e of the guide rail 5, and a guide sprocket 23 provided on the inside of the other bending angles f to h.
The drive sprockets 9 and 22 are interlocked via a reduction gear to cause the chain 21 to travel in the same direction at a slower speed than the chain 6.

Furthermore, the low-speed chain 21 is configured to run directly above the guide groove 13 that has been displaced forward in the processing section c, and a plurality of push pieces 24 for pushing the shaft 18 of the running member 15 are installed below the chain 21. Install with a pitch shorter than the pitch of piece 19.

In this embodiment, the shaft 18 of the member 15 that has entered the processing section c and is separated from the push piece 19 is connected to the low speed chain 2.
One pushing piece 24 pushes each member 15 to move at low speed in a state where they are brought close to each other. Therefore, during this time, wrinkle removal processing is performed on the garment 20, and the garment 20 is separated from the push piece 24 near the end of the processing section c, and is pushed again by the push piece 19, and the garment 20 is fed vertically and exits from the outlet 3.

Furthermore, since only the pushing piece 19 of the drive chain 6 works in the outlet section d, the return section a, and the inlet section b, the operation is exactly the same as in the first embodiment.

In the above-mentioned apparatus, if the wrinkle removing device 1 is replaced with a drying and baking device, and the hook plate is shaped to be suitable for suspending a flat article to be baked and painted, it becomes a device for transporting flat articles to the drying and baking device in a painting line.

In this case as well, the inlet and outlet of the article provided in the drying and baking apparatus can be narrowed to nearly the thickness of the flat article to minimize the amount of the product being discharged outside the apparatus necessary for drying and baking.

Further, as shown in FIG. 10, a guide groove 13 is provided on the upper side of the guide rail 5, the upper end of the shaft 18 fixed to the upper side of the traveling member 15 is made to protrude from the guide groove 13, and the conveyance table 30 is fixed to the upper end, By pushing the shaft 18 with the pushing piece 19 of the chain 6, the conveyance direction and conveyance speed can be changed without changing the orientation of the article 36 placed on the conveyance table 30.

Fig. 11 shows the apparatus of the above embodiment implemented on an assembly inspection line. In this figure, 31 is an incoming conveyor, 32 is an outgoing conveyor, and A is similar to the embodiment shown in Fig. 3. It is a transport device that

In this case, the transport device A is transported by the loading conveyor 31.
The article is transported to the position, placed on the conveyor table 30 at the part, and is inspected by a visual sensor 33, etc., and if it is a good item, the damper 34 is advanced at the part after and the article is transported. The movement of the articles on the table 30 is prevented, only the conveyor table 30 is moved toward the conveyor table 30, and the articles are transferred onto the carry-out conveyor 32.

In addition, in the case of a defective product, the damper 34 is moved together with the conveyor table 30 so that it does not protrude,
It is also possible to collect defective products by pushing them out of the system using a pusher 35 provided between them, or to distribute the products by providing a plurality of pushers 35 and a distribution damper 37.

In this case as well, the posture of the article is always constant, and the necessary parts such as the sensor 33 and pusher 3
In the arrangement portion 5, the moving speed of the conveyor table 30 can be slowed down, so inspection and extrusion can be performed reliably, and the moving speed can be increased in other parts, so processing efficiency can be increased.

(7) Effect This invention runs an endless chain along an endless guide rail, and pushes an article that moves along a guide groove provided in the guide rail with a push piece provided on the endless chain. The rails and guide grooves are rectangular with right-angled bends in the horizontal direction, forming a circulation path, and the running members are square in plan with side surfaces that slide in contact with the inner side walls of the guide rails, so that the required range of the running members can be adjusted. Since the side surface always contacts the inner side wall of the guide rail, the traveling member is always held in a constant direction. Moreover, the traveling locus of the pushing piece at the bending corner of the guide rail is set so that the contact point between the pushing piece and the running member draws an arc concentric with the center of the horizontal plane of the running member, so that the running trajectory of the running member located at the right-angled bending angle is Since the horizontal center line and the center line of each sprocket are aligned, the pusher piece running with the chain does not move the running member when the guide rail turns at right angles, and even if the running direction of the chain changes, the direction of the running member remains unchanged. does not change, and the running member is stopped. When the push piece starts to move linearly with the chain, the running member also starts moving while maintaining a fixed orientation. Therefore, when loading and unloading flat articles such as clothing into a wrinkle removing device, drying or baking device, the front and back sides are fed vertically parallel to the running direction, and inside the wrinkle removing device, the front and back sides are perpendicular to the running direction. When conveying by horizontal feeding,
Since there is no transition part like in the past, there are no accidents caused by drops due to drops, and the height of the device can be lowered.

In addition, in the case where the guide groove provided in the guide rail and the inner side wall are displaced in a direction away from the endless chain at a predetermined portion, the running member is not pushed by the pushing piece of the chain in this part, but is pushed by the following running member. Since it is pushed and moves intermittently, the running speed becomes slower. Therefore, it is suitable for conveyance lines that have sections that require low speeds, such as wrinkle removal sections and dry baking sections.

Furthermore, a low-speed chain with a running speed slower than the endless chain is installed in parallel inside the endless chain provided in the guide rail, and the guide groove of the running member provided in the guide rail is installed in the wrinkle removing device or dryer. Shift the position towards the low speed chain,
In this part, if the moving member is pushed by a push piece of a low-speed chain, and separate chains are used for high-speed conveyance and low-speed conveyance, it is extremely easy to select the conveyance speed of the article to be conveyed. There is an effect that
