Therefore, when chain 1 circulates, it moves completely symmetrically. As shown in FIG. 5, the engaging tools 6, 6' are composed of two engaging pieces 6a facing each other in parallel. It is attached to chain 1 by fixing it to the chain using 1a. And this engagement tool 6,
6' is adapted to move so as to straddle a guide body, which will be described next, with its engaging pieces 6a, 6a on the conveying side (ie, lower side).

Reference numeral 7 denotes the guide body, which is disposed parallel to the frame body 2 with the conveyance side of the chain 1 interposed therebetween, and its proper position is L-shaped supports 8, 8, 8 to the frame body 2. This guide body 7 is plate-shaped, and its starting end side is bent obliquely upward so as to surround the sprocket 4, and furthermore, the tip 7b of the bent portion 7a is formed into a sharp point. Also, the terminal side is chain 1
It ends before reaching the end on the conveyance side, that is, before reaching the sprocket 3, and a discharge pipe 9 is connected obliquely downward to this end 7c.

Note that reference numerals 10 and 11 are limit switches fixed to the frame 2 with appropriate support pieces (not shown), which are activated when a locking device 6 or 6' comes into contact with them. .

The above is the conveyance device, but this conveyance device A is
As shown in FIG. 3, it is installed by fixing the frame body 2 to the projecting pieces 12a of the machine frames 12, 12.

Next, the receiver B and the heat sealing device C will be explained.

13 is a machine frame of the receiver B, and the receiver B consists of this machine frame 13 and a receiving plate 14 stretched over the upper surface of the upper frame 13a.

The machine frame 13 includes the upper frame 13a and the lower frame 13b, an upright frame 13c connecting them, a diagonal frame 13d connecting the upright frame 13c and the lower frame 13b, and the diagonal frame 13d and the upper frame 13a. Side plate 15,1
Since the upper frame 13a is formed with a slight inclination, the upper frame 13a is connected at right angles to the upper frame 13a via a receiving plate 14. The machine frame 1
The conveying device A installed by 2 and 12 is also parallel to the upper frame 13a and tilted upward.

The receiving plate 14 is made of stainless steel, and is stretched at appropriate positions on the upper surface of the upper frame 13a with bolts and nuts. The rear edge of the receiving plate 14 is curved 14a, and both ends of the edge are fixed to the upper part of the upright frame 13c of the machine frame 13 with bolts or nuts, and the front edge 14b is curved 14a. It does not cover the entire upper surface, but ends at a position with an appropriate interval for arranging a heater of a heat sealing device, which will be described later.

16 is the heater, and this heater 1
6 is horizontally suspended at a portion of the upper frame 13a of the machine frame opened by the receiving plate 14, and its upper surface is disposed at approximately the same height as the upper surface of the upper frame 13a.

Reference numeral 17 in FIG. 3 is a receiver for the heater 16, which is made of a roller made of silicone rubber, and both ends of its rotating shaft 18 are integrally formed with side plates 15, 15' hanging below the upper frame 13a. On the other hand, the base portions of the swing arms 19 and 19' are rotatably suspended horizontally between the ends of swing arms 19 and 19', respectively. On the rotation axis of one swing arm 19',
A sprocket 20 is fixed, and this sprocket 20 is rotated via a transmission chain 22 by a motor 21 attached to the same side plate 15', so that swing arms 19' and 1
9 is rotated, so that the receiver 17 is also rotated counterclockwise in FIG.

Bolts 23, 23' are attached to the middle of the swing arms 19, 19', respectively, and between the bolts 23, 23' and the protrusions 24, 24 attached to the side plates 15, 15', as shown in FIG. Each spring 25, 25 is tensioned, and the swing arm 19, 19' is rotated by a motor against the spring force.
When passing the extension line drawn from the protrusion 24 toward the center of rotation of the swing arm, pull the swing arm 19, 19' to release the heater receiving plate 17.
is brought into contact with the top surface of the heater. A timer (not shown) is connected to the motor 21, and the timer causes the motor 21 to rotate for a certain period of time and then stop.

Further, 26 is a limit switch attached to the side plate 15', and this limit switch 26
When the long bolt 23' comes into contact with the bolt 23 of the swing arm 19', the heater 16
is starting to work.

In addition, 27 shown in FIG. 2 is a floodlight attached to the machine frame 12, and 28 is a phototube arranged on the back surface of the receiving plate 14, and the receiving plate 1 corresponding to these is
Holes are drilled at 4 locations.

Next, the operating state of this end pack car will be explained.

First, as shown in FIG. 4, the worker suspends the article 30 to be packaged, such as a coat, on the hanger 29 in advance, and from above hangs the article made of resin film, which has an opening 31a from which the hook 29a of the hanger should protrude. Holding the three-dimensional package 33 formed by placing the packaging bag 32 over the lower end 30a of the object 30, insert the hook 29a protruding from the packaging bag 32 onto the bent portion 7a of the guide body 7 in the conveying device A. I'll hook you.
The hook 29a of the hooked three-dimensional package 33 is
It slides on the upper surface of this bent part 7a and the bent part 7
Since the operation will stop at point c, the operator then turns on a start switch (not shown). This drives the motor 5 of the conveying device A, and the chain 1 circulates clockwise. When the locking tool 6' reaches the bending point 7c of the guide body 7, it straddles the guide body 7 as shown in FIG. It will be caught as shown by the line, and therefore,
The hook 29a of the three-dimensional package 33 is the chain 1
The receiving plate 1 is sandwiched between the guide body 7 and the guide body 7, and is hooked by the locking tool 6' as shown in the imaginary line in FIG.
4, and by the time this three-dimensional package 33 passes over the phototube 28,
The other locking tool 6 reaches the limit switch 10,
This is activated and passed. The limit switch 10 is electrically connected to the phototube 28,
By operating this limit switch 10, the phototube 28 becomes ready for operation. During this time, chain 1 continues to circulate without stopping. Note that the lifting operation of the three-dimensional package 33 is performed smoothly because the receiver B and the transport device A are inclined.

Thereafter, the three-dimensional package 33 is further pulled up onto the receiving plate 14 from the position indicated by the imaginary line in FIG. The light beam constantly emitted from the projector 27 passes through the packaging bag 32 and acts on the phototube 28 to activate it. The actuation of this phototube 28 causes the motor 5 of the conveyance device to stop, thereby stopping the conveyance of the three-dimensional package 33, and at the same time, the moku 21 of the heat sealing device is driven, and the swing arms 19, 19' are moved counterclockwise. It is rotated, and as described above, the spring rings 25 act to press the heater receiver 17 against the upper surface of the heater 16. At this time, the limit switch 26 is actuated by the bolt 23' of the swing arm 19', and current is passed through the heater 16 to cause the object to be packaged to cross the lower end 30a of the packaging bag 32 of the three-dimensional package 33. The hem portion 32a (see FIG. 4) is welded and sealed. After a certain period of time, a timer switch (not shown) connected to the heater 20 is activated, which causes the motor 21 to reverse and return the receiver 17 to its original position, and at the same time, the motor 5 of the conveying device is driven to remove the end pack. The three-dimensional package 33 that has been removed will be further transported.

Thereafter, when the hook 29a of the three-dimensional package 33 reaches the end of the guide body 7, the hook 29a is received by the delivery pipe 9, and the hem of the three-dimensional package 33 slides off the curved part 14a of the receiving plate 14. , the hook 29a slides on the unloading pipe 9, and the three-dimensional package 33 is unloaded to a predetermined position.

On the other hand, the locking tool 6' which has been disengaged from the hook 29a is in a transition state together with the chain 1. At this time, the other locking tool 6 passes through the limit switch 11 and operates the limit switch 11. Therefore, the locking tool 6' stops first at the position where the other locking tool 6 was (see Fig. 2), and the other locking tool 6 first stops at the position where the other locking tool 6 was located. It will stop at the position where ′ is found. That is, since the locking tools 6 and 6' are in symmetrical positions with respect to each other, they have been replaced with those before the operation of the machine, and this completes the process of the end packer. The worker then continues the work by repeating the above-mentioned work.

In the above explanation, the case where the worker feeds the three-dimensional package 33 to the conveyance device of this machine by himself/herself has been explained. If the three-dimensional package supply pipe 34 of a three-dimensional packaging machine (not shown) is connected as shown in FIG. By operating the limit switch, the three-dimensional package is automatically end-packed by the same operation as described above without bothering the operator.

Note that the three-dimensional packaging machine here is a known device that can automatically obtain three-dimensional packages.

(Effects of the Invention) According to the present invention, if a hanger for a three-dimensional package is supplied from below the chain, the hanger is sandwiched between the locking tool and the guide of the chain on the conveyance side and is transferred. The hanger is simply hooked onto a locking device and transported on a guide, but because the guide and chain are tilted upward, the hanger moves as if being pushed from behind by the locking device, and at that time, the hanger moves on the guide. The hanger is transferred while leaning on the tool, and the transfer is carried out smoothly, and the hanger is easily supplied to and discharged from the transfer device due to the arrangement of only the guide and the chain. In addition, the lower part of the three-dimensional package is received by a receiving plate, and a heat sealing device installed on this receiving plate and a device for detecting the sealing position can be used to
It is possible to easily seal the portion of the packaging bag beyond the lower end of the item to be packaged (i.e., the hem portion).

Since the heat-sealed stand-out package has an inclined receiving plate and guide, it can be easily sealed by the receiving plate in a lying state, and the locking tool often supports the hook of the hanger, so that the packaged item cannot be sealed during sealing. Don't move.

However, since the device of the present invention is simply composed of a conveying device and a sealing device, it has a simple structure and is small in size, and has the feature that it can be easily installed in a commercial cleaning shop or the like.
