BACKGROUND OF THE INVENTION
The present invention relates to an article delivery device. For example, the present invention can be applied to a device that transfers confectionery pieces supplied at irregular time intervals to a downstream packaging device at constant time intervals.
[0002]
[Prior art]
FIG. 12 is a plan view of a main part of a conventional article delivery device (FIG. 1 of Patent Document 1).
This is because the article storage unit (10) (10) is connected to the peripheral part of the rotating disk (1) in the circumferential direction from the disc type separation device (A) to the downstream transport device (D). The articles (M) and (M) such as confectionery accommodated in the parts (10) and (10) are transferred at regular intervals.
[0003]
The article (M) (M) received at the receiving position (P1) of the disc separation device (A) is transferred between the disc separation device (A) and the conveyance device (D). A relay device (B) to be transferred to the position (P2) is interposed.
The relay device (B) includes a loop member (2c) that can be bent and circulated between the receiving position (P1) and the transfer position (P2), and a plurality of pieces attached to the loop member (2c) at a constant pitch. A receiving tool (20) (20) is provided.
[0004]
In this case, the receiving side motor (2a) for setting the traveling speed of the loop member (2c) passing through the receiving position (P1) on the outer periphery of the disc type separating device (A), and the transfer position ( A transfer side motor (2b) is provided to keep the speed of the loop member (2c) at P2) constant.
[0005]
Further, the relay device (B) has a loop member (2c) generated between the receiving position (P1) and the transfer position (P2) due to the speed difference between the receiving motor (2a) and the transfer motor (2b). A tension device (2d) for absorbing slack is provided, and the tension device (2d) is a fixed sprocket (S11) provided at two corners located on the diagonal line of the fixed substrate (B0). (S12), a pair of movable sprockets (S2) (S2) supported movably in the horizontal direction by the fixed substrate (B0), and a receiving motor (2a) attached to the fixed substrate (B0). A drive sprocket (S3) to be driven and a drive sprocket (S4) to be driven by the transfer side motor (2b) are provided. Further, the pair of movable sprockets (S2) (S2) is urged in a direction approaching each other by a tension spring (29).
[0006]
In this case, when the article (M) is accommodated in the article accommodating portion (10) passing through the receiving position (P1) on the outer periphery of the disc type separation device (A), the same as the article accommodating portion (10). The loop member (2c) travels at a high speed, whereby the article (M) in the article storage unit (10) passing through the receiving position (P1) is moved to the receiving member (20), (20) of the loop member (2c). ) And is conveyed to the transfer position (P2) of the transfer device (D), and transferred to the transfer device (D) at the transfer position (P2).
[0007]
On the other hand, when the article container (10) that does not contain the article (M) approaches the receiving position (P1) when the rotating disk (1) rotates, based on the signal of the detection sensor (R) that detects this. The receiving tool (20) immediately before reaching the receiving position (P1) is stopped. That is, the drive sprocket (S3) on the receiving position (P1) side is maintained in a stopped state while the drive sprocket (S4) on the transfer position (P2) side is driven. Then, even when the drive sprocket (S3) on the receiving position (P1) side is stopped, the drive sprocket (S4) on the transfer position (P2) side is rotating, so the drive sprocket on the transfer position (P2) side is rotating. The movable sprocket (S2) located between (S4) and the fixed sprocket (S11) moves to the left side of FIG. 12 by the urging force of the tension spring (29), thereby preventing the loop member (2c) from loosening. The The movable sprocket (S2) located between the drive sprocket (S3) on the receiving position (P1) side and the fixed sprocket (S12) is pulled by the drive sprocket (S4) on the transfer position (P2) side. Accordingly, the number of pools of articles (M) and (M) between the driving sprocket (S3) and the stationary sprocket (S12) on the receiving position (P1) side is reduced.
[0008]
Then, when the number of pools of the articles (M) (M) decreases, the rotational speed of the rotating disk (1) and the drive sprocket (S3) increases, and thereby the drive sprocket (S3) and the fixed sprocket (S12 ) And the number of articles (M) (M) to be pooled between (the number of pools) increases, and the movable sprocket (S2) positioned between the drive sprocket (S3) and the fixed sprocket (S12) 29), the loop member (2c) is prevented from loosening.

[0010]
[Problems to be solved by the invention]
However, in the above conventional one, if the rotational speed of the receiving motor (2a) is increased to increase the number of pools of the articles (M) (M) in the relay device (B), a pair of loop members (2c) The region located closer to the disc type separation device (A) than the movable sprockets (S2) and (S2) is accelerated throughout. Therefore, when the number of pools is increased, all the articles (M) (M) and receiving tools (20) (20) in the speed increasing area must be accelerated at once. The load on the side motor (2a) increases. For this reason, in the above-mentioned conventional one, there is a problem that the receiving motor (2a) is increased in size, thereby increasing the size of the entire delivery device.
[0011]
The present invention has been made in view of such points.

[0014]
On the other hand, in the present invention, the rotation operation of the receiving sprocket is controlled based on the article detection signal of the detection sensor that detects the article (M) supplied to the receiving position (P1) by the supply device. Specifically, when the article detection signal is not output from the detection sensor (when the article supply from the supply device to the receiving position (P1) is temporarily interrupted), the receiving motor is decelerated or stopped. The receiving tool (20) engaged with the outer peripheral teeth of the receiving side sprocket is prevented from moving to the receiving position (P1). On the other hand, when the article detection signal is generated, the rotation operation of the receiving sprocket is controlled in conjunction with the receiving motor whose operation is controlled based on the article detecting signal, and thereby the outer peripheral teeth of the receiving sprocket are engaged. The received tool (20) and the detected article (M) are matched at the receiving position (P1).

The Then, the confectionery piece (99) that has reached the receiving position (P1) slides down the chute (110) and is supplied to the receiving tool (20).
[0043]
On the other hand, when the confectionery piece (99) is not accommodated in the article accommodating portion (10) below the confectionery sensor (14) (when the article detection signal is not output from the confectionery sensor (14)), the servo motor (45) Is maintained in a stopped state or a low speed state. Then, the receiving tool (20) engaged with the engaging recess (40) of the receiving-side sprocket (4) in the stopped state or the like is held in the stopped state or the decelerated state, and thereby moved to the receiving position (P1). To be prevented.
[0044]
Therefore, the confectionery pieces (99) (99) are attached to all the receiving tools (20) (20) which are attracted to the metal rollers (74) (74) of the chain (73) and conveyed to the transfer side sprocket (3). It will be set.
[0045]
On the other hand, by the travel of the chain (73), the metal rollers (74) (74) provided on the outer periphery of the chain (73) are permanent magnets (on the lower surface of the block main body (21) of the receiving tool (20)). 27) (27) is attached to the transfer side sprocket (4) and the transfer side sprocket (3). It is transported to the sprocket (3) side and pooled in a closely lined upstream state. Further, the receiving tool (20) existing in the path returning from the transfer side sprocket (3) to the receiving side sprocket (4) is in the state of being adsorbed to the chain (73) in the same manner as described above, and the receiving side sprocket (4). To the side and pooled upstream.
[0046]
In addition, as described above, the lower end judgment sensor (35) and the upper limit judgment sensor are arranged at the tail end of the receiving tools (20) (20) pooled in a closely arranged state upstream of the transfer side sprocket (3). (36) The article supply speed by the disc type separation device (A) is adjusted by the above-described method so as to be maintained at a position between (36).
[0047]
The receiver (20) conveyed to the transfer side sprocket (3) side by the chain (73) is synchronized with the processing operation of the packaging device (C) by the transfer side sprocket (3) as described above. Are sequentially supplied to the packaging device (C) at a speed of Specifically, the confectionery piece (99) supplied to the transfer position (P2) is pushed into the shaping cylinder (92) with the receiving tool (20) at a speed that matches the processing speed of the packaging device (C). The confectionery piece (99) (99) pushed into the shaping cylinder (92) passes through the shaping cylinder (92) together with the packaging film (91) formed into a cylindrical shape, and then the confectionery piece (99) ( Both end edges of the cylindrical packaging film (91) holding the (99) are clamped and welded by the heat rollers (95) and (95). Thereafter, when the long cylindrical packaging film (91) is melted by the rotary cutter (94) (94) in the longitudinal direction for each predetermined dimension, the packaging product (90) filled with the confectionery piece (99) is obtained. can get.
