Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pallet transfer device for transferring a pallet on which a work is placed.

[0002]

[Prior art]

 For example, when manufacturing a small amount of cosmetics, foods, etc. packed in capsule containers, the capsule container placed on a pallet is conveyed by a conveyor in a predetermined direction while filling the object to be filled and the lid film. Are being worn. Conventionally, the pallet for transferring capsules is fixed to the conveyor and cannot be removed during work.

[0003]

[Problems to be solved by the device]

 For this reason, empty pallets remain attached to the conveyor even on the return side, a large number of pallets are required, and the pallets that are not involved in the transport of the capsule container that is the work must also be moved, which requires extra power. There was a problem. Further, if the pallet is still attached to the conveyor, it is not easy to exchange the pallet.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has the following configuration. That is, the pallet transfer device according to the present invention is a pallet transfer device that transfers a pallet loaded with a work by a conveyor that circulates along an endless track in a predetermined section. Detachment means is provided to keep the pallet disengaged from the conveyor in the return section where the pallet is not loaded with workpieces while the conveyor is engaged. It is characterized by the provision of high-speed return means for sending back.

[0005]

[Action]

 The pallet is engaged with the conveyor in the actual transport section where the pallet is loaded with work, and the pallet is removed from the conveyor in the return section where the pallet is not loaded with work. Then, in the return section where the pallet is removed from the conveyor, the pallet is sent back and reused by the high-speed returning means having a higher transfer speed than the conveyor. As a result, the required number of pallets to be used is reduced and the power for driving the conveyor can be reduced. Also, since the pallet can be removed from the conveyor as appropriate, work such as pallet replacement can be easily performed.

【Example】

 As an example of the present invention, a product 4 with a capsule, in which a cosmetic powder 2 is filled in a plastic capsule 1 as an object to be filled, and a lid member 3 made of an aluminum film is attached to the product 4 (see FIG. 9). The pallet transfer device used in the production line will be described.

The pallet transfer device 10 has a configuration shown in FIGS. 1 and 2, and a line conveyor 34 that transfers the pallet 60 in the manufacturing line direction, and returns the pallet 60 in a direction opposite to the manufacturing line direction. A free flow conveyor 74 as a high-speed returning means is provided.

In the line conveyor 34, a plurality of pallet stands 71, ... Are hung at a constant pitch p between a pair of left and right transport chains 70, 70 that move in a predetermined direction along an endless track, and the pallet stands The pallet 60 mounted on the upper side in an engaged state is intermittently moved in the direction B in FIG. 1 by the pitch p. The pallet base 71 and the pallet 60 are engaged with each other by fitting a pair of right and left pins 72, 72 projecting from the pallet base 71 into the pin insertion portions 66, 66 provided on the pallet 60.

The free flow conveyor 74 is provided below the line conveyor 34, and is designed to move continuously in the opposite direction (arrow C direction) at a higher speed (for example, twice) than that of the line conveyor 34. . A roller conveyor or the like is suitable as the free flow conveyor 74.

Further, a detaching cylinder 75, a transfer cylinder 76, and a mounting cylinder 77 are provided as detaching means for detaching and attaching the pallet 60 to the pallet base 71. The pallet 60 conveyed to the terminal end of the line conveyor 34 is pushed out by the detaching cylinder 75 and detached from the pallet base 71. The transfer cylinder 76 holds the separated pallet 60 from the lower side, and the transfer cylinder contracts as it is, so that the pallet 60 is transferred onto the free-flow conveyor 74. The pallet 60 returned to the starting end of the manufacturing line conveyor 34 by the free-flow conveyor 74 is pushed up by the mounting cylinder 77 and mounted on the pallet base 71 again.

As described above, the pallet 60 is conveyed by the line conveyor 34 at a predetermined speed in the actual conveyance section of the manufacturing line, and the return section is returned by the free flow conveyor 74 which is faster than the line conveyor 34. Therefore, the number of required pallets can be reduced. Also. When the free-flow conveyor 74 is a roller conveyor, the pallet is simply placed on the roller conveyor, so that the pallet can be easily replaced.

The pallet 60 on which the work capsules are placed has, for example, the shape shown in FIGS. 3 and 4. That is, it has a rectangular shape in a plan view, and a plurality of capsule holding portions 61, ... Are arranged in a grid pattern (horizontal 10 × vertical 5) on the upper surface thereof. In the capsule holding portion 61, a bush 62 having a shape to which the capsule 1 is just fitted is internally mounted in a state of being elastically supported from below by a spring 63. A push-up pin hole 65 that penetrates vertically is provided at the center of the bush 62. Normally, when the capsule 1 is fitted into the bush 62, the upper portion of the capsule 1 is in a state of slightly projecting from the upper surface of the pallet 60. Further, at the left and right ends of the pallet 60, there are formed pin insertion portions 66, 66 for opening the pallet on the pallet base 71, the positioning pins projecting upward at the same position. 67, 67 are provided. Further, at least one of the side surface portions is formed with a convex side surface mark 68 1, ... Corresponding to the position of the capsule holding portions 61 ,.
